This sounds like the thing to do.  Since there is only 1 selection at a 
time you shouldn't have to worry with anything but updating the hidden 
field with the id.  The one thing I might add is to set up the dropdown 
with a blank element as the first row so the onselect event will fire 
and update the hidden.  Otherwise, if you have  an element that shows 
up in the dropdown as the first element you probably want to set the 
hidden in the onLoad event to the first item in the dropdown.

HTH,
