The host that my client is using has display_errors On and I receive
notices of undefined variables and indexes. Also, register_globals is
On. I've included snippets of the lines that the notices refer to in my
code below.

What I have done is taken repetative code and bunched it into a seperate
file. Then I include that file(s) into the page(s) that need them. In
this situation I go to signup.php, which has common.php and formvars.php
included in it.

Are these serious programming issues? If I need to improve how I have
written this and anything in the future, I would like to know how to.

I would appreciate any help or suggestions.

Thanks,
Pasquale
