I am evaluating your smith-registration-pro (4.50.0) software for online donation and product sales, but get below error when I submit the form.

I am using Evalon Virtual Merchant as the gateway and my test amounts have been $1 and $100.00 Message : The amount supplied in the authorization request appears to be invalid.
Please advice and thanks for your time.
