Browser freezes when ''Clear on being hidden'' option is selected

When ''Clear on being hidden'' or ''Clear on submit'' is selected, the browser freezes when trying to edit the form. I need to clear hidden fields in order to make payment options work.

Thanks

Generally, the issue happens when there are more fields and conditions set on the form. As I check your JotForm, I see that there are about 210 fields and 40 conditions set on the forms. Please note that when the value of a field set with a condition is changed, all the associated conditions will be triggered sometimes cause cascading effect based on the conditions set. I have cloned the form to my account and was able to replicate the issue. As I tried disabled some of the calculation conditions, the form seems to be loading normally. 

Please review the conditions set on the form once and see if you can make use of Form calculation widget to perform calculations right on the form without using conditions. Let us know if you need any further assistance. We will be happy to assist.
