This seems to be a simple request, But I could not find anything on the web of how to accomplish it.
I have two drop down selection fields which I would like to be able to put a value on the "qty" field and the " level" field add together and show the result in the cost field on the output form.
Here is the code
<td width="320"><span class="style5">Total Cost:</span><span class="style3">
<input name="cost" type="text" id="cost" size="25" />
<td width="342"><span class="style3">Referees </span><span class="style1">:</span> <span class="style3">
<select name="qty" size="1">
<option value="Qty" selected="selected">Qty</option>
<option value=" One ">One</option>
<option value=" Two ">Two</option>
</select>
</span></td>
</tr>
<tr>
<td><span class="style3">Game Level :</span> <span class="style3">
<select name ="level" size="1">
<option value="Mite">Mite</option>
<option value="Squirt">Squirt</option>
<option value="PeeWee">Pee Wee</option>
<option value="Bantam">Bantam</option>
<option value="Midget">Midget</option>
<option value="Middle School">Middle School</option>
</select>
</span></td>
</tr>
