Your statement:
IF Abs.late==0 AND Abs.absent==0 AND Abs.early==0
MESSAGEBOX('You need to make a non-zero entry') + CHR(13) + ;
'in either Late:, Absent:, or Early:', 0+48+0, 'Error')

I believe you closed the ")" to early try the following
IF Abs.late==0 AND Abs.absent==0 AND Abs.early==0
=MESSAGEBOX('You need to make a non-zero entry' + CHR(13) + ;
'in either Late:, Absent:, or Early:', 0+48+0, 'Error')
ENDIF
