Hello, and thank you for your assistance. I guess I'm not 100% sure where the Translate function needs to go. This was what i had tried
translate(WorkZip[Company = Title], "abcdefghijklmnopqrstuvwxyz", "ABCDEFGHIJKLMNOPQRSTUVWXYZ")
This is a rule to set a fields value (VendorPostalCode) when the drop-down (Company) is equal to (Title) which is the Column in SP which has the company name.
The Main Data Source field to store the PostalCode is (VendorPostalCode) and the Secondary Data Source is (WorkZip)
Using the above rule does NOT populate the VendorPostalCode field.
EDIT - Stupid unrelated mistake on my part. This did work....I guess I DID actually know what I was doing. Thanks again for the time!
