I recorded the following macro

Sub Macro1()
'

'

'
Application.Goto Reference:="Print_Area"
Selection.Borders(xlDiagonalDown).LineStyle = xlNone
Selection.Borders(xlDiagonalUp).LineStyle = xlNone
With Selection.Borders(xlEdgeLeft)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
With Selection.Borders(xlEdgeTop)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
With Selection.Borders(xlEdgeBottom)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
With Selection.Borders(xlEdgeRight)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
With Selection.Borders(xlInsideVertical)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
With Selection.Borders(xlInsideHorizontal)
.LineStyle = xlContinuous
.Weight = xlHairline
.ColorIndex = 1
End With
Columns("A:W").Select
Columns("A:W").EntireColumn.AutoFit
End Sub

PrintArea is a portion of a Pivot Table

The macro works fine as long as the workbook remains open. After I close
the workbook, and subsequently open it at a later time, the macro fails on
the statement

..LineStyle = xlContinuous

with a message that states

Runtime error 1004

Unable to set the line style of the border class.

Any help would be appreciated.
