Re: Another PHP problem

Sorry guys, guess I wasn't clear enough.  The problem stems from the fact 
that every link in the script contains "...&site=$site..." or "...&site=<?PHP 
echo ($site); ?>...."    Site is being passed to the first page in the URL, 
like: http://www.narrowgauge.f2s.com/phorum?site=pwp.

If however, $site has not been set in the URL, errors occur because it 
doesn't know what to print in the links.  Therefore, if $site has not been 
set I need a way to set it, but make it empty (so that $site= ).  Am I making 
sense???

Thanks for your time.
