Please use the # to add code tags when posting code.
Both the code I posted and Andrew's Cancel addition will delete autonumbered texts, if those sentences complete a paragraph. If they don't then you will also need to remove the numbering e.g
Code:
Sub Delete_Sentence_if_Word_found()
Dim strTexts As String, oRng As Range, iResponse As Integer
strTexts = InputBox("Enter texts to be found here: ", , "continued")
Set oRng = ActiveDocument.Range
With oRng.Find
.ClearFormatting
.Replacement.ClearFormatting
While .Execute(findText:=strTexts)
oRng.Expand Unit:=wdSentence
oRng.Select
ActiveDocument.ActiveWindow.ScrollIntoView oRng, True
iResponse = MsgBox("Are you sure to delete the sentence?", vbYesNoCancel)
If iResponse = vbYes Then
oRng.Text = ""
oRng.ListFormat.RemoveNumbers
ElseIf iResponse = vbCancel Then
Exit Sub
End If
oRng.Collapse wdCollapseEnd
Wend
End With
lbl_Exit:
Set oRng = Nothing
Exit Sub
End Sub
Without knowing what is in the paragraphs you can only program on the basis of what you do know.
