I am trying to do the same thing and had a few additional issues. All your select boxes are named the same. I'd like to be able to name them sel1, sel2, sel3, sel4, sel5, etc. I also need to compare the drop downs against hidden fields, they would be named the same. So I would have the following form and not want to allow duplicates:

<form name="myform">
<input type="hidden" name="sel1" value="1">
<select name="sel2">
<option value="0">Select Option A </option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>
<select name="sel3">
<option value="0">Select Option B </option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>
<select name="sel4">
<option value="0">Select Option C </option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>
<select name="sel5">
<option value="0">Select Option C </option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>
<input type="hidden" name="sel6" value="5">
<select name="sel7">
<option value="0">Select Option E </option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
</select>
</form>

Hii MillerTime

ofcourse you can do this,
in this case u need to put sel1, sel2 etc in the code.and you can compare with hidden sel6 value.
if possible can you tell us where is exactly u getting problem.
