Displaying popup list on form

[George]

On my form there is a field 'client_id' that is defined to be a pop-up list which displays values from a field. I have chosen to use values from 'client_id' and display values from 'name'. This works fine locally but when trying to select a client by browser, I can only see the client_id and not also the name field.

How can I get this to display both client ID and Name field?

Fraid to say that relational value list don't work using Instant Web Publishing, a frustration of mine as well - Ubo
