HI
You can figure this out so you can work with one file. It's much
easier to maintain.
Here is an example. It's a simple RSVP form. ***Change line 100 to
use your own email address to receive the information. I wrote this
a while back so I'm not bragging about the html format or coding but
it works. It uses a more primitive series of IF's to test the input
rather than the IF - ELSEIF - ELSE series I described earlier. In
this example, remember the first time through, pg is blank (which is
<2).
Good Luck.
