When you click on “Make Payment” below and are sent to PayPal’s PayFlow Link site to complete your payment, you should avoid any characters that are not simple letters and numbers. No accented characters (á, ç, ü); no spaces, dashes (‐), or other punctuation in credit card numbers or security codes; no parentheses (), brackets [], braces {}, ampersands &, etc. in any field except for the ‘@’ in an email address. If you encounter problems with the PayPal form, double-check that you have not included any of these characters that may not be handled properly by PayPal.
