syntax error

hi lads, i’m trouble with an error message that i can’t resolve. The error is on line 91 of this code, it would seem to be a syntax error but i can’t see it. Any takers?

I highlighted the area in question with the tag (line 91 error) in the code, but i feel the error maybe just before that…i’m not sure thou, i have only been using php steadily for about a month now. The error i receive is
