20
into 'Sheet1' D1

					Select Sheet1 D1
20
now enter this formula
=IF(AND(A1:A20=Sheet2!A1:A20),Sheet2!D1
20,"")
not just enter, use Ctrl + Shift + Enter
 
				
			 
			 
			
				
			
		 
		
		
	 
								
								
									
	
	
								
								
									
	
								
							
							 
							
								
	
	
							
						 
					
					 
				
			 
		
	 
	
	
					
					
				
					
					
						
	
	
	
	
	
		
			 
			 
		
		 
		
			
				
					
				
				
					
					
						
							
								
	
	
							
							
							
								
									
	
	
	
								
								
									
	
	
		
		
			
				
			
			
				
					Hi,
Welcome to the world of array formula. You must follow the instruction on
how to enter the formula precisely.
Select D1 to D20 on sheet 1 and then paste this formula into the formula bar.
=IF(COUNTIF(A1:A20,Sheet2!A1:A20)=20,Sheet2!D1
20,"")
Now very important hold down CTRL & Shift keys and tap enter. If you've done
it correctly then Excel will have put curly brackets around the formula {}.
