A user may begin a donation form and receive a validation message for required information that was not entered on the form. When the form is reloading the user may notice that the donation amount field has changed from the number originally input to a different number.
This behavior can only be duplicated using the Chrome web browser on a Mac. The card expiration date is being autofilled by chrome into the donation amount field when the form reloads. The issue is caused by a chrome Bug for certain Mac operating systems where specific conditions are met by the end user.
