Hugh,
Food? What's that?
[Btw, my wife would love you. She seems to think I spend too much time in
here . . .]
Thanks for the help. I sort of figured I'd have to make a php page to call
the error codes, then call another for the actual database stuff. At least,
I'll be able to find my errors quicker. Later, when I understand things a bit
better, I'll clean up that mess! [I've actualy got three forms working now --
I'm amazed!]
Gosh, the output is ugly, though! I can't seem to line up the input boxes
with those horrible "nbsp" and since the text name before it varies . . .
sigh . . . someday I'll figure that out!
Regards,
Andre
