I need to be able to get the selected inputs from four different
selections and based on those 4 selections, post a part number in another text field (e21b)within the same form.


<div class="formcss1">

<option value=”101”> 19.5"</option>
<option value=”110”> 22.5"</option>
<option value=”120”> 24.5"</option>
</select>

<label id="e25" class="cc47" for="e26"> Bolt Holes </label>
<select id="e26" class="cc48" size="1" name="Title" title="Title">
<option value=”201”> 8</option>
<option value=”210”> 10</option>
</select>
