Auto-Complete on a drop-down box

[SallyBullard]

I am an Access developer moving to FMPro and there is a basic tool that I can't seem to duplicate. I want to create a drop-down box for Customer Name, but store the Customer ID. I want the user to be able to type the first few letters of the name and have it cycle through the list so they don't have to scroll through 8,000 names. I have tried Manage Lists with the first field (CustomerID) stored and only show the second field (Customer Name), but then the auto-complete doesn't work. This is so basic, I must be missing something. WHAT IS IT!!!! PLEASE!!!
