Re: Radio Button Troubles

This worked well but it stopped screen messages from appearing.  The program
used to display messages when an item was not found but they do not show
anymore.  When I take out the changes they work fine again.  Is there a fix
for this that you know of?  I tried putting in a check for non blank fields
but that seems to generate errors before the screen is displayed.
