Don't forget that there's a distinction between the name displayed on screen and the way Santa pronounces it (display vs. audio). The name displayed is exactly the one you've entered in the form—not the one selected as a pronunciation.
However, if you are using special characters in the first page of the form (e.g. Arabic, Chinese, etc.), it's possible that the characters are not supported in Santa's Big Book. Please make sure the spelling of the name is exact in the form and no characters outside the Roman alphabet are being used.
NOTE: You can always go back and edit this. Find out how HERE.
