My total copy cost field is not calculating total.

Hello,  You all have been great with all my questions, thank you!  I just responded to another thread saying my form wouldn't register the 3rd decimal place even after you tested- I finally got the test form to work so all good there.

However, I cannot get the 'Total Copy cost' field to calculate and I don't see why it the formula i have in wouldn't work.  Can you please advise?  I've included a screen shot below.

thanks so much

I cloned your form and removing the comma separate and adding it back resolves the issue. Please try that and see if that works on your form as well.

Looking forward for your response.
