Syntax error: Encountered ";"
<p>I'm trying to output my tic tac toe game results to a database. However I keep running into this error whenever a match between two clients is completed. Here's an excerpt of my code from the server side and the error message:</p>

<p>What does Encountered ";" mean, and what can I do to rectify it?</p>
