VBA Code throwing Compile Error: Expected Array - excel

Question

I have a CSV file that contains lots of tables inside of one worksheet. I was writing parts of the code in one procedure to check if it was doing what I expected for each table. The final result I pasted in one single procedure and now I'm getting a Compile Error right in the beginning of the code, in "Sub IP_VBA()", and I have no idea how to solve it, can someone help me?
If I run it part by part, it does what I want, but not when I put all the code together.
Sub IP_VBA()
' Format IP table
Dim LR1 As Long, LR2 As Long, LR3 As Long, LR4 As Long, LR5 As Long
Dim FR1 As Long, FR2 As Long, FR3 As Long, FR4 As Long
Dim Rows As Long, i As Long
Dim Data As Range
'Delete tables 1, 2 and 3
Rows("1:3").EntireRow.Delete
Rows("1:1").Select
Range(Selection, Selection.End(xlDown).Offset(1, 0)).Delete Shift:=xlUp
Rows("1:2").EntireRow.Delete
Columns("A:I").EntireColumn.Delete
'Get necessary data from table 4
LR1 = ActiveSheet.Range("A1").CurrentRegion.Rows.Count
Range("B1:B" & LR1 & "," & "D1:E" & LR1 & "," _
& "G1:O" & LR1).Delete Shift:=xlToLeft
'Delete table 5
Rows(LR1 + 2).Select
Range(Selection, Selection.End(xlDown).Offset(1, 0)).Delete Shift:=xlUp
'Get necessary data from table 6
FR1 = Range("A" & LR1).Offset(2, 0).Row
Rows(FR1).EntireRow.Delete
LR2 = ActiveSheet.Range("A" & FR1).CurrentRegion.Rows.Count + LR1 + 1
Range("A" & FR1 & ":B" & LR2 & "," & "E" & FR1 & ":J" & LR2 & "," & _
"L" & FR1 & ":T" & LR2).Delete Shift:=xlToLeft
'Get necessary data from tables 7 and 8
FR2 = Range("A" & LR2).Offset(2, 0).Row
Rows(FR2).EntireRow.Delete
LR3 = ActiveSheet.Range("A" & FR2).CurrentRegion.Rows.Count + LR2 + 1
FR3 = Range("A" & LR3).Offset(2, 0).Row
Rows(FR3).EntireRow.Delete
LR3 = ActiveSheet.Range("A" & FR3).CurrentRegion.Rows.Count + LR3 + 1
Range("A" & FR2 & ":D" & LR3 & "," & "G" & FR2 & ":L" & LR3 & "," & _
"N" & FR2 & ":V" & LR3).Delete Shift:=xlToLeft
'Delete table 9
FR4 = Range("A" & LR3).Offset(2, 0).Row
LR4 = ActiveSheet.Range("A" & FR4).CurrentRegion.Rows.Count + LR3 + 1
Range("A" & FR4 & ":W" & LR4).Delete Shift:=xlToLeft
'Delete Empty Rows
LR5 = ActiveSheet.Cells(ActiveSheet.Rows.Count, "A").End(xlUp).Row
Set Data = ActiveSheet.Range("A1:C" & LR5)
Rows = Data.Rows.Count
For i = Rows To 1 Step (-1)
If WorksheetFunction.CountA(Data.Rows(i)) = 0 Then Data.Rows(i).Delete
Next
'Rename Columns
Range("A1").Formula = "Part Number"
Range("B1").Formula = "IP Qty"
Range("C1").Formula = "IP Value"
End Sub

Answer 1

You have
Dim Rows As Long
but then
Rows("1:3").EntireRow.Delete
I would not use Rows as a variable name, and also use a specific worksheet qualifier for any and all calls to Rows/Range/Cells/Columns
Dim ws As Worksheet
Set ws = ActiveSheet
ws.Rows("1:3").EntireRow.Delete
'etc
