First, if you have a new question, please don't piggyback on someone else's thread.
Second, If you read Marshall's response to the original question you should realize that your structure is incorrect. You should NOT have Zip, Office, Address, State in your main table. Only EmployeeID.
Did you read my blog on Displaying data as mentioned in my response here? It goes into several ways to do this properly.
Finally, you say "it only populate the zip field", Do you mean the ZIP control on your form or the ZIP field in your table. You don't have fields on a form, you have controls that may or may not be bound to fields in a table.
The code you are running shouldn't be in the change event but in the After Update event. To know why this doesn't work, we need to know the RowSource of your combo and the controlsource of your controls. Please start a new question with the additional info needed and we will try to help.
