Hello,
I am working on a personal project for my profession.
In Excel, I have text items in dropdown lists that I wish to assign numeric values. Each item will have an independent decimal value. What I am wanting to do is set it up so that when an item is selected from a list, it's numeric value (which I do not wish to be visible) can be applied to a math formula is several cells elsewhere in the project.

In the screenshot above, I have a lot of information (I'll clean it up later). However, what I want to do is in the dropdown menu under Film Class (upper left) I want each Class type to have its own numeric value that corresponds to the values in the table highlighted in yellow.
Also, if it is relevant, please be aware that I currently have two dropdown menus in the upper left. They are dynamic. Under Film Brand, when a different selection from the menu list is made, the list under Film Class changes accordingly. Not sure if it matters in this question, but I thought I'd include this detail in case it does.
I did look through the forum and found a few similar questions with answers, but I didn't get the results I wanted when I tired some of the solutions. So, I decided to post my question for my case specifically.
I may likely have future questions as I progress in this project. Thanks for any assistance!
