total not displaying for payment field

hello, my form was working correctly but suddenly , i check that total amount is 0 even i click on product . can you check this . please Thankyou

It seems there is an issue with the form itself. I notice that there are some modifications being done on this form for the last three days. As I check the form revision history of this form, the total of the products selected is not being displayed from the beginning. As I check your other JotForm in the account http://www.jotformeu.com/form/60684240549358, I see that the total is working fine. 

You may clone this form again, and change the theme to match your requirement. Please let us know if you need any further assistance.
