I have a form where clients can select their preferred plan. I have used checkboxes and set the export value to the plan cost, which then gets tallied at the bottom. However, I now need to make the value of the plans editable so the sales agents can sell the plans for whatever price they choose to. How do I make the checkbox exported value match the text field of the price?
That's not the way to go about it. What you should do is use a script that checks if a box is ticked, and if so, adds the value in the corresponding text field to the total, instead of trying to edit the export value of the box itself.
