I created a list of 500 codes (Vouncher). I will use it for mine school when the student will use the wireless network. The student will ask for a WLAN voucher.
When the teacher type in the students name, class, date and klick on print.
I will that the infromation that the teacher typed in and the vouncher will be saved in an other sheet. And the sheet with the vouncher will be updated with a mark on the used vouncher or delete the row.

Any tips will be welcome!!
