Combo Box and Hilited Pick

[Jeff Honken]

I have a combo Box.  The box has several items in it.  When I choose
what item has been picked I use:

get the selectedText of btn "PayType"

How do I "set" the button for a menu choice?  I have items such as PPO
and HMO in the combo box choices.

I'm looking for something like:

Set the selectedText of btn "PayType" to "PPO"

But I would like it to work.  Jeff
