Re: [WDSCI-L] Radio Button Troubles

["Mark Giordano" <mgiordano@xxxxxxxxxxxxxxxxxxx>]

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.
