I'm trying to do a countif formula between a specific range of years, while referencing from an alternate sheet. 
    
        
            
    
This is the sheet with all my data (of course, just a small example)
    
        
            
    
And this is the range within which I'm trying to work. For 1976-2000, the formula I have is 
=COUNTIFS({Game Design Range 2}, >=1976), but trying to add 
{Game Design Range 2}, <=2000
as the second criterion gives me #UNPARSABLE. Anyone have any tips/way to get what I'm looking for? Thanks in advance!
