I made where the bracket matches checked fine in my Editor. However, the 
bracket problem was a bit more than just a missing bracket; I misplaced 
them and badly.

No arguement there.

Well, I unfortunetaly don't have a C history, but I do often the find 
the ! operator quite useful and often a way to have less code in that 
often no ELSE is needed that way. Which BTW is now my current interest; 
minimizing the amount of code used and still have it more or less 
self-documenting.

Cheers,

From my limited perspective, your greatest gap is in techniques for
systematically identifying errors. The two most recent were: not being
checking if session variables were making it to the script, and
unbalanced parentheses. The methods for finding these types of errors
are not language-specific.

That looks familiar; as in, the sample I wasn't able to re-find; Thanks 
Much! The sample code was, I think, an isset() or a mail() setup, but 
same difference.

Hmm, thanks. I'll look into those formats.

Thanks much,
