Hi
Your criteria range
Sheets("new").Range(lr, lc)

is one cell.
Do you mean

Sheets("new").Select
lr = Cells(65536, 1).End(xlUp).Row
lc = Range("IV1").End(xlToLeft).Column

With Sheets("new")
'note the dots. No need to select and it won't help
Set CritRange = .Range(.Cells(1, 1), .Cells(lr, lc))
end with
Sheets("old").Select
Range("A1:p1044").AdvancedFilter Action:=xlFilterInPlace,
CriteriaRange:= _
Critrange, Unique:=False

regards
Paul
