Payment preview always shows $100 on a giving form

In GiveCampus giving forms, available controls depend on your permissions and the interface used by your institution.

The payment-preview action creates a sample Test Donor contribution with a fixed $100 value. It does not carry a real amount from the preceding prepayment preview. This is sample rendering, not evidence that live checkout ignores selected amounts. Verify the actual donor form through an approved test flow and avoid unintended payment. A real checkout amount mismatch needs its own reproduction and configuration review.
