can you post a link where I can see this?
It sounds like you want to make the corner booth, electric hookup or sales spot a check box in your add to cart button? is this correct?
In the add to cart button, go to the bindings panel, select the corner booth, electric hookup or sales spot columns and select the Updateable as Checkbox option. This will add the checkbox to the add to cart form.
In design View, you will need to select each of the checkboxes, and set the Checked Value in the property inspector to "yes" (without the quotes).
