Your code is assuming global Result (student id from the camera scan) will have a successful lookup result that is in the downlaoded list of ids.
You need to capture the index into the list of ids, and check if it is non-zero before attempting to use it to look up other sttributes of the student in question from your spreadsheet data.
You might include a Notifier popup presenting the unexpected id and complaining that it isn’t recognized.

You create global id as an empty list, add list item/s to it, then use this (a list) as an index (which should be an integer)
