Copying range of second dynamic table - excel

Question

I have two tables placed in many sheets. I go through the sheets copying the data from one of the two tables. The range can vary, so it is not something I can statically code the range.
Each table ends in "Total" so that was the string I was attempting to find in the column and setting the last row equal to "Total's" row.
How do I copy the range of my second table (green background). These tables will not be the same range for each sheet.
I have set it up so the 'addSetB' which copies the first table (blue background) by copying the range and ending at "Total". So for 'addSetC' I tried setting it up so it will begin copying after the first total and stop at the second table, grabbing the range of the second table.
Is there a better way to accomplish this? Or how should I go about fixing my current code?
I get
runtime error 91: "Object variable or With block variable not set".
Highlighting the 'startRow' line.
Updated Sub addSetC() code. Now throwing:
Runtime-error: 1004 "Application-defined or object-defined error"
for ActiveSheet.Range("L" & startRow & ":Q" & lastRow).Copy after implementing BigBen's suggestion.
Table layout
' Copy range of the green background (not working / throwing errors)
Sub addSetC()
Dim lastL As Long
lastL = ActiveSheet.Range("L" & rows.Count).End(xlUp).row
Dim FoundRow As Range
Dim startRow As Integer
Dim lastRow As Integer
Dim rng As Range
With ActiveSheet.Range("L2:L" & lastL)
'Set startRow to first "Total"
Set rng = .Find(What:="Total", LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious)
If Not rng Is Nothing Then startRow = rng.row
'Set lastRow to second "Total"
Set rng = .Find(What:="Total", _
After:=.Cells(1), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False)
If Not rng Is Nothing Then lastRow = rng.row
ActiveSheet.Range("L" & startRow & ":Q" & lastRow).Copy
End With
Sheets("DATA").Activate
Cells(Range("A" & rows.Count).End(xlUp).row + 1, 1).PasteSpecial xlPasteValues
Application.CutCopyMode = False
End Sub
The above code is not copying the second table.
Here's what I used to copy the first table (blue background) which is working. How do implement this in my other subroutine to copy the other table?
' Copy range of blue background (functioning properly)
Sub addSetB()
Dim lastRow As Integer
lastRow = Cells.Find(What:="Total", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).row
Range("L3:Q" & lastRow).Copy
Sheets("DATA").Activate
Cells(Range("A" & rows.Count).End(xlUp).row + 1, 1).PasteSpecial xlPasteValues
Application.CutCopyMode = False
End Sub
