Try this instead. I couldn't get Devon's to work on my system either, but
this one does. Note the use of the empty() function which tests a string
for emptiness.
Let me know if it works?

Subject: [PHP-WIN] Re: WinXP Error Passing Variables (and creating)
No offense taken, but I have never done this before so I don't really know
what I'm doing with the variable passing and stuff (aside from C++ and VB
knowledge). I copied that from the book exactly and it did not work.
Your form does not work either, it simply gives me the else statement's
actions ("No data yet, or $username is empty."). I do believe I hit the bug
they were talking about and am now thinking of getting Linux from my boss
too install and run for PHP. Thanks for the help.
