However, all the options should be closed.
Instead of: <OPTION VALUE="1">History
Use: <OPTION VALUE="1">History</OPTION>
Also, you should move the <OPTION>Choose Categories...</option> out of
the select or you'll get it as an array item if someone actually selects
it. You could I guess set it to disabled also.
