Problem with database providers

Here's what I ended up doing.  I created a separate code template with two value holders.  One was used for the display and one for the SRL.  The trick was to change the SRL value holder to use "All - No Selection".  Then it always retrieved the value I needed (if there ends up being two rows with the same value for the description but different keys, then I hope the testing catches it).  That way, each time the selected value changed, the code value changed with it.  I didn't need to write a custom provider after all (client is not fond of those because of the testing cycle for the code).

     Thanks for all your help,
