Find Function VBA Named Argument Not Found-Runtime error 448

[meibr2]

I am writing a macro( late binding) that runs through a word document and highlight all the values that is contained in my cell range in Excel. I have used the find function which works fine until I add the argument IgnoreSpace:= True, which I don't understand why it's resulting in error. Appreciate any help

Sub Highlight()
    Dim lrow As Long
    lrow = Sheet1.Range("A" & Rows.Count).End(xlUp).Row
     Dim i As Long
       Dim myRange As Object
        Dim FindText As Object

        Set myRange = ActiveDocument.Content


       For i = 1 To lrow Step 1

       myRange.Find.Execute FindText:=Sheet1.Range("A" & i).Value, MatchCase:=False, _
        IgnoreSpace:=True, Forward:=True, MatchWholeWord:=True

      If myRange.Find.Found = True Then myRange.HighlightColorIndex = wdYellow
      Next i
      End Sub

I've never thought Microsoft's documentation was good, but this is the first time I've seen it flat-out wrong.
