binding an excel spreadsheet to a drop-down

[amyl54731319]

I'm working on a complex form and my goal would be to have a drop-down where the user can choose a name and a corresponding telephone number would populate in another field. I thought I could do this by binding an excel spreadsheet but it's not working. Is this something that is possible? Am I doing something wrong and not binding correctly? maybe a different way to produce the outcome? There are about 85 names/numbers that need to be included.
