When I try to run a Word macro named UpdateTOC, I receive a "Run time error
'5678': Word cannot find the requested bookmark." message.

When I click the "debug" button, I'm taken to this line within the code:

"Selection.GoTo What:=wdGoToBookmark, Name:="toc""

This is the rest of the code:

```````````````````
Sub UpdateTOC()

   Selection.HomeKey Unit:=wdStory
   Selection.GoTo What:=wdGoToBookmark, Name:="toc"
   With ActiveDocument.Bookmarks
       .DefaultSorting = wdSortByName
       .ShowHidden = False
   End With
   
   ActiveWindow.View.ShowFieldCodes = Not ActiveWindow.View.ShowFieldCodes
   Selection.EndKey Unit:=wdLine, Extend:=wdExtend
   Selection.Delete Unit:=wdCharacter, Count:=1
   
   ActiveWindow.View.ShowFieldCodes = Not ActiveWindow.View.ShowFieldCodes
   With ActiveDocument
       .TablesOfContents.Add Range:=Selection.Range,
RightAlignPageNumbers:= _
           True, UseHeadingStyles:=True, UpperHeadingLevel:=1, _
           LowerHeadingLevel:=4, IncludePageNumbers:=True, AddedStyles:=""
       .TablesOfContents(1).TabLeader = wdTabLeaderDots
   End With
   
   Selection.HomeKey Unit:=wdStory
   Selection.GoTo What:=wdGoToBookmark, Name:="tocend"
   With ActiveDocument.Bookmarks
       .DefaultSorting = wdSortByName
       .ShowHidden = False
   End With
   Selection.MoveLeft Unit:=wdCharacter, Count:=1
   Selection.TypeParagraph
   
End Sub
`````````````
Can anyone provide any insight in two what is going on or attempting to
happen?  I have no experience in VB coding, so laymans terms may be necessary
to explain it.  ;-)

Thanks.
