Help with INDEX and MATCH statements.
 

I have the following formula in a spreadsheet.
=INDEX(Hours!$A$1:$AD$48,MATCH((Masterschdule!$B4) ,Hours!$A$1:$A$48,0)MATCH($R$3,Hours!$A$1:$AD$1,0) )
The formula works unless I change the row sort. It treats the "$B4" cell
referance as an absolute. the "B" colume should not change but I need the
row"4" to change with the sort. Why does it not update the formula when I
change the sort?
