Validation and Selectboxes!!!

Hi,

I am trying to validate the following form so that a selectbox option can only be selected once on the form (i.e. no 2 selectboxes can have the same option select). But I have absoloutly no idea how to go about it, Help with this will be much appreciated.

<form name=”InsertFixtures” method=”post” action=”” onSubmit=”return ValidateSelect(this)”>

<table width=”96%” border=”1″ height=”189″>
<tr>
<td colspan=”2″ height=”54″>
<div align=”center”><b>Insert Fixture</b></div>
</td>
</tr>
<tr>
<td height=”23″ width=”49%”>
<div align=”center”>Home Team</div>
</td>
<td width=”51%” height=”23″>
<div align=”center”>Away Team</div>
</td>
</tr>
