Combining 2 separate codes into one

[julhs]

Due to my limited skills with VBA I have to resort to solving individual elements of my FINAL code.
This maybe a potentially floored method, but not much different than using “Record Macro” for hints.
Yet again I’m looking for help to combine two separate WORKING codes into ONE.
Had a lot of help with the separate aspects of the different elements.
I know where the problem lies but I can’t resolve it.

Code doesn’t bug out, it just fails/doesn’t complete the copying/pasting stage.
Because as code stands it is not passing the ACTUAL USED RANGE ($S$10:$S$337) from the first section of code to the second.

Dim sht As Worksheet
Dim lastcell As Range, firstcell As Range
Dim lastRow As Long, firstRow As Long
Dim findString As String
Dim LstUsedRow As Variant
Dim FstUsedCell  As Variant

Dim Usedcells As Long  ' Range Long Variant Integer
Dim Frow As Long, Lrow As Long, DestRow As Long, i As Integer
Dim rng As Range, r As Range
Dim copyCells As Range, pasteRng As Range        
                                        'Application.ScreenUpdating = False  ' re-apply when testing complete
    Set sht = ThisWorkbook.ActiveSheet
            ' This is to clear the Destination range before a new paste
            '  it first finds the row beneath target row with "Cash Paid" in column T
        Frow = sht.Range("T:T").Find(what:="Cash Paid", LookIn:=xlValues, LookAt:=xlWhole).Row
            'This finds the ACTUAL last row based on column T
        Lrow = sht.Cells(sht.Rows.Count, "T").End(xlUp).Row
        sht.Range("ar" & Frow + 1 & ":AT" & Lrow).Clear '  Is the Results/Destination area/range to clear
