I have a form, in it I have a combo box to determine the tax rate.
HTML Code:
 <select name="tax" size="1">
        <option value=".0775">7.75%</option>
        <option value=".08">8%</option>
...
    </select>
I created a checkbox next to any items price to determine if that product is taxed. How can I update the Total to include tax (if its selected)?
Thanks...
