You can add as many values (rows) as you want. The value on the left, if a delivery, should have the word "deliver" in it so the script knows to also check for address fields. The value on the left should be simple and ideally alphanumeric. The value on the right shows on the page, and can be descriptive.<br /><br />
<b>Sample:</b><br />
left: deliver wed early<br />
right: Wednesday Delivery 9am-Noon
