Delete text within two bookmarks

[dugdugdug]

Assuming I have the following text:

Hello,

"BOOKMARK_START"

What are you doing

'BOOKMARK_END"

Call me

I want to delete the text within two bookmarks in Word to end up with:

Hello,

Call me

I found this code:

Dim pRange
Dim dRange
Dim myrange

pRange = ActiveDocument.Bookmarks("BOOKMARK_START").Range.Start
dRange = ActiveDocument.Bookmarks("BOOKMARK_END").Range.End
Set myrange = ActiveDocument.Range(Start:=pRange, End:=dRange)
myrange.Cut

What happens when the code is run is BOOKMARK_START and BOOKMARK_END point to the same place, (which is BOOKMARK_START), ie:

Hello,

BOOKMARK_START / BOOKMARK_END

Call me

Next time I insert something into BOOKMARK_START (and then try to delete it), it won't recognise BOOKARK_END (because it's the same location as BOOKMARK_START).

How can I get round this?
