Using Excel to Calculate Meeting Attendance by Organization

[hming]

I need some help!! I'm not sure if it's possible to calculate attendance by organization and not by person. For example, I don't care how many people have attended a meeting for each office, because if one person from an office attends a meeting, that office is credited 100% for attending a meeting. So if an invite was sent out to 4 people in the same office and only one person attended they have fulfilled their requirement for that office. Is that possible to show that in excel where I can calculate that for each quarter?

@hming If I understood correctly that could be something like this:

=IF(B2<>0,1,0)

or shorter,

=--(B2<>0)

Drag down as far as needed and format as %.
