If your pledge has errored, here are a few things to take a look at before trying your pledge again:
1. Check that you entered a valid credit card number and the correct expiration date (and make sure it's not expired).
2. Confirm that your billing address and phone number are correct.
3. Make sure you haven't exceeded the credit limit on your card.
If everything seems to check out, it’s possible your bank has put a hold on the charge. Please contact your bank to authorize the pledge.
Additionally, sometimes browser issues can prevent a pledge from going through. I would suggest resetting your web browser by clearing your cache and cookies, and checking for available updates. If the issue persists I would try it in a different web browser altogether.
