What is the exact error that you're getting PAT? The way I entered my name during my online appointment booking is I typed it in capital letters. Good thing I only have one first name so it's easy to type. For instance, if the name is JUAN MANUEL DELACRUZ then write it as is. Put JUAN MANUEL in the GIVEN NAMES(S) text box and DELACRUZ in the SURNAME text boxHow many times did you try?
