Re: [WEB400] painful question on javascript and checkboxes not working

["Brad Stone" <brad@xxxxxxxxxxxx>]

I would debug your javascript.  You'll probably find the
problem there.

Also, one note.  If you really don't need a count of the
number of checkboxes and are just checking to see if any
were checked, I would have your AnyRecords() method just
reuturn TRUE if it finds a checked box (in the loop), and
FALSE at the end of the loop.  This will speed things up a
little and make the code a little clearer.
