I am trying to use Excel to create a very simple 'counter' interface for operators. Essentially when they find something in one of the categories listed, they push that button and it sends a 1 count to PI. However, when I built the macro in excel it works just fine for me but none of my coworkers can use it. Even when I open up the file on a tablet I cannot use the macro without getting an error. Has anyone else ran into this issue? If so how did you resolve it?
