Why is the form payment different from what Paypal shows after submission?

I created a registration form with a payment option of $250.  I registered my daughter and the paypal screen that comes up after the registration said $300.  Is this paypal error or Jotform problem?  Please advise.

There's a chance that when you tested it, the Non-Refundable Deposit (which amounts to $50) was also ticked when you submitted the form, thus causing it to cost $300.

Please test it again with only the Full Amount ticked as shown above. If you still see $300 as the total in Paypal, kindly get back to us with a screenshot of both the form (prior to submission) and Paypal screen (after submission) so we can have a closer look.
