Testing the Mortgage Calculator
This simple mortgage calculator is a great example of an application that uses a browser-enabled InfoPath form hosted in the InfoPath Form Web Part for entering and validating data, and an Excel workbook hosted in the Excel Web Access Web Part to perform complex calculations. By connecting the Web Parts, you can send the data that a user enters in the form to the Excel workbook.
This walkthrough consists of the following high-level steps:
Publishing the Loan Amortization sample template from Microsoft Excel 2010 to a document library in a site on Microsoft SharePoint Server 2010 using Excel Services.
Designing and publishing a browser-enabled form from Microsoft InfoPath 2010 to a document library in a site on SharePoint Server 2010.
Creating a Web Part page, adding the InfoPath Form Web Part and Excel Web Access Web Part to the page, and then defining the connections between the two Web Parts.
Testing the mortgage calculator page.
Follow the steps below to create a mortgage calculator on a Web Part page with the InfoPath and Excel Web Parts.
Publishing the Loan Amortization Workbook to Excel Services
To provide a workbook to perform calculations, publish a workbook based on the Loan Amortization sample template to a document library on SharePoint Server 2010 using Excel Services. To enable the workbook to work correctly with the Excel Web Access Web Part, you must remove protection and data validation from the workbook before publishing it. To provide a way to send data from the InfoPath Form Web Part to the workbook, you configure which cells to use as parameters for receiving data.
To publish the Loan Amortization workbook to Excel Services
Open Excel 2010, and then click the File tab.
Click New, click Sample Templates, and then double-click Loan Amortization.
On the Review tab, click Unprotect Sheet.
On the Home tab, click Find & Select, and then click Go to Special.
Click Data Validation, click All, and then click OK. This selects all of the cells in the workbook that contain data validation.
On the Data tab, click Data Validation.
At the prompt The selection contains more than one type of validation. Erase current settings and continue?, click OK.
In the Data Validation dialog box, click Clear All, and then click OK.
Click the File tab, click Save & Send, click Save to SharePoint, and then click the Browse for a location button.
Type the URL for a document library in the SharePoint Server 2010 site where you want to create the mortgage calculator Web Part page.
Make sure the Open with Excel in the browser check box is selected, and then click the Publish Options button.
On the Parameters tab, click Add, and then select the following named ranges in the Add Parameters dialog box: Interest_Rate, Loan_Amount, Loan_Start, Loan_Years, and Num_Pmt_Per_Year.
Click OK twice, enter a name for the workbook, and then click Save to publish the workbook to the SharePoint document library with Excel Services.
In the next section, you will create and publish a browser-enabled form that will be used to send data from the InfoPath Form Web Part.
Designing and Publishing the Form
To provide a browser-enabled form for entering data to send to the Loan Amortization workbook, use InfoPath 2010 to create the form described in the following steps, and then publish it to a document library in a site on SharePoint Server 2010.
To design and publish the form
Open InfoPath 2010, and double-click the Blank Form form template under Popular Form Templates on the New tab.
In the Fields task pane, right-click myFields, click Add, type InterestRate, and then click OK. Repeat this step to add the following four fields: LoanAmount, LoanStart, LoanYears, and NumPmtPerYear.
Drag the five fields from the Fields task pane to add them as Text Box controls to the form.
Add a Button control to the form, and on the Properties tab in the ribbon change the Label of the button to Send Data.
On the Properties tab, click Rules.
In the Rules task pane, click New, and then click Action.
Click Add, click Send data to Web Part, and then click Property Promotion.
Click Add next to the list that is below the text The fields below will be available as SharePoint Web Part connection parameters.
Select one of the five fields, set Parameter type to Output, and then click OK. Repeat this step for each of the remaining fields, and then click OK to close the Form Options dialog box.
Click OK to close the Rule Details dialog box.
Click the File tab, click Publish, and then click SharePoint Server.
Name the form LoanForm, and then click Save.
Step through the Publishing Wizard to publish the form template in a form library on the same SharePoint Server 2010 site where you published the Loan Amortization workbook.
In the next section, you will create a Web Part page, and add the InfoPath Form Web Part and the Excel Web Access Web Part to the page.
Creating a Web Part Page and Configuring the Web Parts

Testing the Mortgage Calculator
Now that all the components of the mortgage calculator are on the Web Part page, you can test it.
To test the Mortgage Calculator
Open the Web Part page that contains the two Web Parts in the browser.
Enter values in the form displayed in the InfoPath Form Web Part, and then click the Send Data button.
The values entered in the InfoPath Form Web Part should be sent to the Excel Web Access Web Part, and the calculations in the workbook should be performed on those values.
