Stripe error "Invalid Integer: NaN"

This is very weird because I've had 40+ form submissions with no issues, but one use keeps getting this error.

I've added "Round" to the calculation widget but it's still happening. 

Any suggestions? Thanks!

I cloned the form and could not replicate the issue. i could use the round function successfully.
Cloned form can be found at https://form.jotform.com/70670985840970

Hope this helps.

Thank you.

Thanks Ian.

The error message was only appearing for one client. Perhaps it was cached (and the error came when they entered their credit card details, apparently not from the rounding at all - even more strange). Not to worry. I sent them a manual invoice.
