Hi,

I have 2 select menus, each containing several number amounts.

Example:

Code:
    <select name="total_weekday" id="total_weekday" onchange="this.form.total.value=calculateTotal(this);">
      <option value="0">0</option>
      <option value="1812.5">1</option>

      <option value="3625">2</option>
      <option value="5437.5">3</option>
      <option value="7250">4</option>
      <option value="9062.5">5</option>
      <option value="10875">6</option>
    </select>


    <select name="total_weekend" id="total_weekend" onchange="this.form.total.value=calculateTotal(this);">
      <option value="0">0</option>
      <option value="2265.625">1</option>

      <option value="4531.25">2</option>
      <option value="6796.875">3</option>
      <option value="9062.5">4</option>
      <option value="11328.125">5</option>
      <option value="13593.75">6</option>
    </select>
What I want to do is when you select one option from each menu it adds the values together, and puts them into a text field.

How can I do this?

Thanks!
