Hi there, 
I have created a Sales Activity Tracker - where I want to show the number of new leads we had between two specific dates. 
So in the sales activity tracker - I will have two cells - one with the starting date and one with the end date.
And in my master sheet - I have a column named "Date Leads In" with the date for each lead. 
I tried to use the COUNTIF formula but so far it's not working:  
=COUNTIF({Flat file - final Range 1},=<[Starting Date]2, {Flat file - final Range 1}=>[End Date]2)
Knowing that...
Flat file - final Range 1
is the name it gave me when I link to another sheet named
Flate file - final
and I've selected the column that has the dates when we got a new lead. 
And 
[Starting Date]2
is the cell - where the starting date is
and 
[End Date]2
is the cell - where the end date is
 
THANKS FOR YOU HELP!!
