I was trying to find if result of concatenation is duplicate or not but the formula is not working. Below is the formula that I create. pls help in rectifying the error.
IF(COUNTIF(VALUE(CONCATENATE($E$2:$E$1048576,$M$2:$M$1048576,LEFT($AP$2:$AP$1048576,2))),VALUE(CONCATENATE($E$2:$E$1048576,$M$2:$M$1048576,LEFT($AP$2:$AP$1048576,2))))>1,"Yes","No")
IF(COUNTIF(VALUE(CONCATENATE($E$2:$E$1048576,$M$2:$M$1048576,LEFT($AP$2:$AP$1048576,2))),VALUE(CONCATENATE($E$2:$E$1048576,$M$2:$M$1048576,LEFT($AP$2:$AP$1048576,2))))>1,"Yes","No")
