I was able to find that the & symbol is the seperator between multiple
variables. It is working now. I still haven't found confirmation that
only one set of POST or GET variables can exist at one time. If this is
true, I wonder how the problem is handled at larger companies where
multiple POST forms could make up a site. Certainly they don't resort
to URL GET as I could see how the strings could be quite long in some
cases.
