Validation for Radio buttons

[prakus]

I have the a FORM for rearranging some records (number of records is dynamic).

The code for the Form is :

<Form name='RearrangeSectionForm' Method='POST' Action='includes/updateSectionOrder.asp' onsubmit='return checkRadios(this);'>
<table width='90%' align='left'>
<tr><td width='20%' align='center' valign='top'><b>Current Order</b></td>
<td width='30%' align='center' valign='top'><b>Section Name</b></td>
<td width='50%' align='center' valign='top'><b>Desired Order</b></td></tr>
<tr><td width='20%' align='center' valign='top'><b>&nbsp;</b></td>
<td width='30%' align='center' valign='top'><b>&nbsp;</b></td><td width='50%' align='center' valign='top'><b>&nbsp;&nbsp;1&nbsp;&nbsp;&nbsp;&nbsp;2&nbsp;&nbsp;&nbsp;&nbsp;3&nbsp;&nbsp;</b></td></tr>
<tr><td width='20%' align='center' valign='top'>1</td>
<td width='30%' align='center' valign='top'>sec1</td>
<td width='50%' align='center' valign='top'>
<input type='radio' value='1' name='R1' ID='Radio1'>
<input type='radio' value='2' name='R1' ID='Radio1'>
<input type='radio' value='3' name='R1' ID='Radio1'>
</td></tr>
<tr><td width='20%' align='center' valign='top'>2</td>
<td width='30%' align='center' valign='top'>sec 2</td>
<td width='50%' align='center' valign='top'>
<input type='radio' value='1' name='R2' ID='Radio2'>
<input type='radio' value='2' name='R2' ID='Radio2'>
<input type='radio' value='3' name='R2' ID='Radio2'>
</td></tr>
<tr><td width='20%' align='center' valign='top'>3</td>
<td width='30%' align='center' valign='top'>sec 3</td>
<td width='50%' align='center' valign='top'>
<input type='radio' value='1' name='R3' ID='Radio3'>
<input type='radio' value='2' name='R3' ID='Radio3'>
<input type='radio' value='3' name='R3' ID='Radio3'>
</td></tr>
<tr><td width='20%'></td><td width='30%'></td><td width='50%' align='center' valign='top'><br><br><input type='submit' value='Update Section Order' name='Save'></td></tr></table></Form>

I have some validation code to make sure that atleast one radio button is checked in each radio group.

I need to validate that only one radio button is checked in each radio group having the same order( or value). (i.e., if Radio group R1 is checked and has a value of 2, then R2 and R3 should not have any radio button checked with value =2. Please remember that the set of Radio buttons is dynamic but will always have the same number of rows and columns.

Any help will be greatly appreciated.
Thank you.

call a function using onClick on the last set of radio buttons and then check the other values using a getElementByID and then display appropriate message if need be

I can manage to include the onClick with the radio buttons.
I need some sample code for the validation using the getElementByID.

Thank you.
