You have not changed the issue that is causing the error i.e.
Code:
StrTxt = ActiveDocument.Path & "" & StrTxt
If the document has been saved, the activedocument path would be e.g. "C:\Path".
If you add strTxt to this, the resulting path is "C:\pathstrTxt", whereas it should be "C:\path\strTxt"
Code:
StrTxt = ActiveDocument.Path & "\" & StrTxt
Ensure the document is saved before running the macro.
Code:
