I actually got it to work until I got the error "Only positive integer allowed." I then changed the value to "ID" which worked, but not when I want to reference the that drop down from a text field.
So let's say I have a drop down of a,b,c,d and if I select "d" I want that value to display in my text box below the drop down. If I change the value in the drop down to "ID" I can only get a number in the test box.
The drop down it getting it's data from the same list. So I setup a Data connection for it to point too.
