Inherited code does not work in FF3+

[pastor_rick]

I inherited a search engine program just after FireFox released v2.0.0.1 at which time everything was working properly. Now however, the program works in IE but the ratings system hangs (never finishes) when the user tries to vote for their favorite message board when using FF. Below is the code snippet called “ratings.php” which I think must be the culprit but I see nothing there which could (or should) cause this behavior in either php4 or php5… can anyone here help?
