I get the above message when I click on an hyperlink cell with the following
codes:

End With
Worksheets("Bucket SiteList").Select
ActiveSheet.Range("C3:E3").Select
With Selection
.WrapText = False
End With
ActiveSheet.Range("B5").Select

End Sub

This is the code that I used to hyperlink the cells:
Sub createHYPERLINKS()
Dim c As Range, ws As Worksheet

For Each ws In ThisWorkbook.Worksheets
If ws.Name = "DDS Bucket" Then
ws.Select
For Each c In ws.Range("E4:K62").Cells
c.Select
If c.Value 0 Then
With ActiveSheet
.Hyperlinks.Add Anchor:=Selection, Address:="",
SubAddress:=ws.Name & c.Address
End With
With Selection.Font
.Name = "Calibri"
.FontStyle = "Bold Italic"
.Size = 11
'.Underline = xlUnderlineStyleSingle
'.Color = 16711680
End With
End If
Next c
ws.Range("B2") = Date
ElseIf ws.Name = "SWOPS_FOPS Bucket" Or ws.Name = "TRANSPORT_SDDI
Bucket" Then
ws.Select
For Each c In ws.Range("E4:I62").Cells
c.Select
If c.Value 0 Then
With ActiveSheet
.Hyperlinks.Add Anchor:=Selection, Address:="",
SubAddress:=ws.Name & c.Address
End With
With Selection.Font
.Name = "Calibri"
.FontStyle = "Bold Italic"
.Size = 11
'.Underline = xlUnderlineStyleSingle
'.Color = 16711680
End With
End If
Next c
ws.Range("B2") = Date
End If
Next ws
End Sub

The codes still work fine, when I click the "Ok" button on the "Reference is
not valid" dialog window.
Any ideas will be greatly appreciated.
Thank you
