Hi, I'm trying to use the countif formula to count but with 2 criteria.
I have colum A and colum B
Colum A Colum B
QDT True
QDS True
QDT False
QDG True
QDS True
QDT False
etc... etc...
I need to count the #of QDT which is True in colum C but seems unable to add the "AND" function withing the Countif function
any help ?
