Question:
Need to find total sales in Jan-08,Feb-08,March-08 for salesman=Lawrence and Region=West using VLOOKUP,INDEX&MATCH functiions??
Already solved using SUMIFS,SUMPRODUCT,SUM Functions,what i need is i am stuck in using INDEX&MATCH,VLOOKUP.
Just check my formula to make changes:
Here columns B=Month C=Salesman,D=Region E=Product
=INDEX($G$4:$G$1082,MATCH(U4&W4&{“Jan-08″,”Feb-08″,”Mar-08”},($C$4:$C$1082)&($D$4:$D$1082)&($B$4:$B$1082),0))
=VLOOKUP(U4&W4&{“Jan-08″,”Feb-08″,”Mar-08”},CHOOSE({1,2},$C$4:$C$1082&$D$4:$D$1082&$B$4:$B$1082,$G$4:$G$1082),2,0)
