Excel error message"one or more named invalid references" - excel

Question

I cannot find the named range or reference that is invalid, according to Excel. I checked my named ranges, including ranges within charts. The excel file contains a macro that creates a report that works fine when launched within the file itself. However, if I call that function from another workbook to run the report that is when I get the error message of invalid references. When going through the reports created both directly and indirectly they seem identical. Setting Application.DisplayAlerts = False does not work.
I tried using the code below from from Allen Wyatt to go through all reference and none refer to outside sheets nor contain any errors.
Sub CheckReferences()
' Check for possible missing or erroneous links in
' formulas and list possible errors in a summary sheet
Dim iSh As Integer
Dim sShName As String
Dim sht As Worksheet
Dim c, sChar As String
Dim rng As Range
Dim i As Integer, j As Integer
Dim wks As Worksheet
Dim sChr As String, addr As String
Dim sFormula As String, scVal As String
Dim lNewRow As Long
Dim vHeaders
vHeaders = Array("Sheet Name", "Cell", "Cell Value", "Formula")
'check if 'Summary' worksheet is in workbook
'and if so, delete it
With Application
.ScreenUpdating = False
.DisplayAlerts = False
.Calculation = xlCalculationManual
End With
For i = 1 To Worksheets.Count
If Worksheets(i).Name = "Summary" Then
Worksheets(i).Delete
End If
Next i
iSh = Worksheets.Count
'create a new summary sheet
Sheets.Add After:=Sheets(iSh)
Sheets(Sheets.Count).Name = "Summary"
With Sheets("Summary")
Range("A1:D1") = vHeaders
End With
lNewRow = 2
' this will not work if the sheet is protected,
' assume that sheet should not be changed; so ignore it
On Error Resume Next
For i = 1 To iSh
sShName = Worksheets(i).Name
Application.Goto Sheets(sShName).Cells(1, 1)
Set rng = Cells.SpecialCells(xlCellTypeFormulas, 23)
For Each c In rng
addr = c.Address
sFormula = c.Formula
scVal = c.Text
For j = 1 To Len(c.Formula)
sChr = Mid(c.Formula, j, 1)
If sChr = "[" Or sChr = "!" Or _
IsError(c) Then
'write values to summary sheet
With Sheets("Summary")
.Cells(lNewRow, 1) = sShName
.Cells(lNewRow, 2) = addr
.Cells(lNewRow, 3) = scVal
.Cells(lNewRow, 4) = "'" & sFormula
End With
lNewRow = lNewRow + 1
Exit For
End If
Next j
Next c
Next i
' housekeeping
With Application
.ScreenUpdating = True
.DisplayAlerts = True
.Calculation = xlCalculationAutomatic
End With
' tidy up
Sheets("Summary").Select
Columns("A:D").EntireColumn.AutoFit
Range("A1:D1").Font.Bold = True
Range("A2").Select
End Sub
