As a complete VBA novice, I want to overwrite some Bookmarked text with
specific AutoText and retain the Bookmark (so I can repeat this Macro if/when
rqrd).

I have manged so far to generate the following simple code:

Sub CHOOSE_TEXT()
'
' SLT Macro
'
   Selection.GoTo What:=wdGoToBookmark, Name:="LTXT"
   Selection.Find.ClearFormatting
   With Selection.Find
       .Text = ""
       .Replacement.Text = ""
       .Forward = True
       .Wrap = wdFindContinue
       .Format = False
       .MatchCase = False
       .MatchWholeWord = False
       .MatchWildcards = False
       .MatchSoundsLike = False
       .MatchAllWordForms = False
   End With
   With ActiveDocument
   If .FormFields("Dropdown1").Result = "Specification No." Then
   Application.DisplayAutoCompleteTips = True
   NormalTemplate.AutoTextEntries("SLT").Insert Where:=Selection.Range, _
       RichText:=True
   Else
   Application.DisplayAutoCompleteTips = True
   NormalTemplate.AutoTextEntries("QLT").Insert Where:=Selection.Range, _
       RichText:=True
   End If
   End With
End Sub

The above Macro is run on exit from a dropdown box in a form within an
earlier protected section of the document.

UNFORTUNATELY if the Bookmark "LTXT" is text then the macro only works once
as it obliterates the Bookmark along with the text.

IF the bookmark "LTXT" is just a position within the document then the macro
will happily re-run - BUT it doesn't replace text (it just pushes it down the
document, which is not acceptable).

CAN ANYONE HELP, PLEASE?

Rgds,
