Field visibility

Using Pro 8 I have created a form for ordering tickets to a breakfast. I have the field validations and calculations all working as they should.

My problem is that some people will complete the form online, print it and just mail it in with a check. On the other hand, some will print it out (or be sent a printed version) and fill it out by hand. Therein lies my problem. The total fields show "$0.00" even when the rest of the form is empty. While that does not matter for those completing it by machine, it is problematic for those completing it by hand.

So, my question is simply this: Is there any way to have the calculated totals NOT be visible unless they are greater than 0.00?

Thanks
