I was making a simple issue difficult. All I had to do was
a. Set the Browse Mode checkbox under Field entry
b. Put a Commit Record step into the script which toggles the radio button
(I forgot that IWP doesn't change values in the database until the layout changes or an explicit Commit Record step is executed.)
Cool deal that it seems like you solved your own problem! My issue is that I would like to understand a bit better how you accomplished this. Could you explain a bit further how you designs the button and created the script to toggle a hidden field on and off? I am assuming you are using the hidden potral trick to make the field visible and unvisible. If not, could you share your method also? Thanks.
