Validate the Total amount

My form will have multiple products. However, I don't want to allow users to submit it until the total amount is 15$ or more. Is there a way to add such validation?

Hi,

You will not be able to do it directly using the Purchase Order tool.

Instead use Calculation field so that you can assign conditional statement that can validate the current Total amount.

Check this user guide http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field

Here is a demo form you can check http://form.jotform.me/form/42522161797457?

 

In the test form, if the Total Amount is less than 15.00 , you will not be able to submit the form.

Hope this help. Inform us if you need further assistance.

Thanks!

 

Right…. I understand, but if I do it that way, that means I cannot add a payment tool to the form.. correct

...

No, it's not correct. We now have a way to collect an actual payment while configuring your product items using Radio, Dropdown or Checkbox fields.

You can add a payment tool and forward the total amount using the calculation widget. We have a guide for that:
