Payment form does not calculate the total amount correctly.

What's wrong with this form payment process?

Everything totals up just fine until I check the box for Sponsorship - Canvas Bags.  When I check that box, the purchase total is changed to '0', no matter how many different items are purchased.

The mentioned product (and the other Sponsor products) have a wrong property configured in it that is causing this behavior.

I presume that you wanted to use a quantity property like in the other products.

I suggest you to take a look at the following guide: https://www.jotform.com/help/225-How-to-add-options-to-Payment-Forms 

I've also created this cloned version of your form: http://form.jotformpro.com/form/50886332356965 so you can see how it should be configured. Feel free to clone this form to your account to check it further.

Let us know if you need further assistance. We'll be happy to provide it.

Thank you, but no, I did not want it be a quantity property.  I'm not sure what was the cause of the malfunction, but I deleted the existing property and re-entered it again as a custom property and the form now works properly.

Thanks again.

Ok, Thank you for letting us know.
I'm glad that your form is working ok now.

If you need our help again, feel free to contact us anytime.
