Hello,
I'm quite weak at PHP, so I was hoping to get some help understanding the
below code. First off, I'm trying to create a "query form" that will allow
me to display the results on my screen. I grabbed this code from the net
hoping that I could tweak it for my needs. I'm using MySQL, PHP and IIS and
they all are running fine. As the code is, it will display the form, but it
won't display my result(s). Any suggestions?
Cheers,
