fill in a column with data from another tab

[istniettisleute]

I am looking for a way to fill in column G in Tab1 as simply as possible with the data from Tab 3.
If the name matches, i.e. column A and column B in Tab 3 are equal to column B and column C in Tab 1, a 1 should appear in column G instead of a 0.

Any ideas?

Thanks in advance!

Try this in G4:

=COUNTIFS(Omloop!A:A,B4,Omloop!B:B,C4)

Drag the formula down column G.
