Validation and Selectboxes!!!

[warkem]

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>

you have two sets of select boxes,did you mean you wanted unique selection between the 2 slect boxes for each group or all four must have unique value?
