Hi,

Im trying to make the price appear in a text box in a form when the user selects the quantity from a drop down box. The price is fixed at 38.50. Any help is highly appreciated, here is the code in my form (I havent attempted any javascript yet - and Im sure my code for the form is bad too!) :

<form action="" method="post">

 <tr align="left">
              <td width="118"><span class="style3">Quantity</span>
                  <select name="Product 1" size="1">
                    <option selected="selected">0 </option>
                    <option>1 </option>
                    <option>2 </option>
                    <option>3 </option>
                    <option>4 </option>
                    <option>5 </option>
                    <option>6 </option>
                    <option>7 </option>
                    <option>8 </option>
                    <option>9</option>
                  </select>
                  <input type="hidden" name="Product 1" value="38.50" />
<input name="hidden" type="text" value="Price" size="1" /></td>
				  </tr>
</form>
