make a change in cost of submission

I set this form up awhile ago and can't remember....How do I change so that each submission costs $75 instead of $50

I got it working somewhat...they all add $75 except the first one still says $50?

Hi,

I tried to check your form and it looks to have been deleted.  If you still need some help with one of your forms, let us know which one you are working on and we will be happy to have a look.
