Your procedure seems to work here. You could try to simplifiy:
Code:
Sub COPYPAR()
Dim oPar As Paragraph, oRng As Range
Set oPar = Selection.Paragraphs(1)
Set oRng = oPar.Range
With oRng.Find
.ClearFormatting
.Text = "="
If .Execute Then
oRng.Start = oPar.Range.Start
oPar.Range.InsertAfter oRng.FormattedText & vbCr
End If
End With
lbl_Exit:
Exit Sub
End Sub
