I am trying to keep track of student movement throughout the day. I have created a spread sheet for each classroom that students will sign out on, I have then used the =importrange() function to grab all data from each classroom, now I am trying to use =countifs() to search through all of these sheets and match student names and dates and give me a total. On my master sheet I want to type a Student Name in A2 and then a date in B2, then use the countifs function to run through the sheets and give me a total. Each time it keeps returning "0".
I have the following: =countifs(Krohn!A:A,A2,Krohn!C:C,"*"&B2&"*")
Here is a link to the sheets.
