Hi, i’am a french teacher of technologie and i want to create a glide apps for my student.
i’ve got a lot of different questions:

When my student repairs a machine. they must edit a report with different data (name,description of the problem, name of the system, technologie,duration of the intervention,…). i make a sheet repport allow user to edit then a pencil appear but it’s not working.
