So i set up a table that i would like to use. I'm not sure where to go from here.

<table width="951" border="0">
  <tr>
    <th width="145" scope="col">Part Description</th>
    <th width="155" scope="col">Quantity</th>
    <th width="155" scope="col">New/Old</th>
    <th width="153" scope="col">Quoted Price</th>
    <th width="160" scope="col">Aker Price</th>
    <th width="143" scope="col">Part #</th>
  </tr>
  <tr>
    <td><form id="form1" name="form1" method="post" action="">
      <label>
        <div align="center">
          <select name="Part Description" id="Part Description">
            <option>ACL 5500</option>
            <option>ACL 5100</option>
            <option>Profire 1100</option>
            <option>FGI 351</option>
          </select>
        </div>
      </label>
    </form></td>
    <td><form id="form2" name="form2" method="post" action="">
      <label>
        <div align="center">
          <select name="Quantity" id="Quantity">
            <option>0</option>
            <option>1</option>
            <option>2</option>
            <option>3</option>
            <option>4</option>
            <option>5</option>
          </select>
        </div>
      </label>
    </form></td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>

</table>

when i select from the product menu i would like a stored list to popup in one of the different columns.

for example, if i selected ACL 5500, i would like for a price to automatically pop up in the quoted price column and multiply that number according to the quantity i select.

is there something i should be looking for, it's been years since ive done anything with javascript and i am completly lost right now.

i am using dreamweaver cs4 to do this as well.
