Error on automating data entry - vba

Question

I recorded a macro & integrated together with some codes I researched and tested, which worked individually. However, having combined them all together, I stumbled across errors running the macro. Pop out a message box which displays
Compile Error: Expected End With
Would appreciate all the help I could get to solve it
Sub Book1UpdateDelete()

' Book1UpdateDelete Macro

' Keyboard Shortcut: Ctrl+g

'Select values in a column from specified workbook and sheet
Dim LR As Long, cell As Range, rng As Range
Windows("Y738 Data").Activate
With Sheets("Graph data")
LR = .Range("B" & Rows.Count).End(xlUp).Row
For Each cell In .Range("B4:B" & LR)
If cell.Value <> "" Then
If rng Is Nothing Then
Set rng = cell
Else
Set rng = Union(rng, cell)
End If
End If
Next cell
rng.Select
End With
Selection.Copy
'Open next workbook
Windows("Y783").Activate
'Open Sheet L
Sheets("L").Select
'Select empty field fromn column AA
Range("AA" & Rows.Count).End(xlUp).Offset(1).Select
'paste selection to empty field
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
'Go back to previous workbook & delete column
Windows("Y738").Activate
With Sheets("Graph data")
Columns("B:B").Select
Application.CutCopyMode = False
Selection.Delete Shift:=xlToLeft
Sheets("Graph Data").Select
End Sub

You've missed and end with at the bottom of your code.
Try this (untested)
Sub Book1UpdateDelete()
'
' Book1UpdateDelete Macro
'
' Keyboard Shortcut: Ctrl+g
'
'Select values in a column from specified workbook and sheet
Dim LR As Long, cell As Range, rng As Range
Windows("Y738 Data").Activate
With Sheets("Graph data")
LR = .Range("B" & Rows.Count).End(xlUp).Row
For Each cell In .Range("B4:B" & LR)
If cell.Value <> "" Then
If rng Is Nothing Then
Set rng = cell
Else
Set rng = Union(rng, cell)
End If
End If
Next cell
rng.Select
End With
Selection.Copy
'Open next workbook
Windows("Y783").Activate
'Open Sheet L
Sheets("L").Select
'Select empty field fromn column AA
Range("AA" & Rows.Count).End(xlUp).Offset(1).Select
'paste selection to empty field
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
'Go back to previous workbook & delete column
Windows("Y738").Activate
With Sheets("Graph data")
Columns("B:B").Select
Application.CutCopyMode = False
Selection.Delete Shift:=xlToLeft
Sheets("Graph Data").Select
End with
End Sub
