Validate minimum order value from a form.
I have made a simple form with WA form tool, which has two products that the user can select number from. The products have different prices.
I want the form to validate the total amount (from both products). If it is less than 100, it should not be possible to send the order and a message should say that the minimum order value is 100.
How to create this?
Since this is a common way, there should be a pretty easy way to do this - or?
