Replace in specific range - simple solution needed

Hi all,
I've tried to find a solution to this but can't.

Range columns C:F

replace

What:="$AL$3:$AL$42", Replacement:="$AM$3:$AM$42"

sheet2

Cannot find a simple solution to this!!!

Use Excel's built up function. CTRL plus H

Sub macro_1()
Sheets("Sheet2").Range("C:F").Replace What:="$AL$3:$AL$42", Replacement:="$AM$3:$AM$42"
End Sub
