= SUM('A & E John Super'!$P$4:$P$39)/SUM('A & E John Super'!$L$4:$Q$39)
where =IF(ISERROR((VLOOKUP(A12,'share detail'!$D$2:$D$52,1,
FALSE))),"",I12&J12) is on the A & E John Super worksheet
there are values on the AEJohn worksheet but they are not adding up on the
other worksheet. do i need another reference or ' or something?
thanks
