Copy formula depending on a different column

[The_Rock]

Hi
Hoping you guys can help with the below.

So what the code is doing is it is searching for 'Global Name' in Col M and then moves down a row to where the formula's are stored.
I then want to copy the formula's down for the number of rows in Col L.
I can't find the right code to do as it is mixing relative references with fixed??

Note: Global Name can appear in any cell in Column M which is why I am using search and offset.

  ''Find first line of formula and copy down
    Columns("M:M").EntireColumn.Select
    Selection.Find(What:="Global Name", After:=ActiveCell, LookIn:=xlFormulas _
        , LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
        MatchCase:=False, SearchFormat:=False).Activate
    
    ActiveCell.Offset(1, 0).Range("A1:C1").Select
    Range(Selection, Selection.End(xlDown)).Select
    Selection.FillDown

Appreciate your help.
Thanks
