I have this code:

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim arr() As Variant
On Error GoTo eh
Application.EnableEvents = False
For cnt1 = 1 To target.value.words.count
arr(cnt1) = Target.Value.words(cnt1)
If IsNumeric(arr(cnt1)) Or arr(cnt1) < "+" Or arr(cnt1) < "-" Or arr(cnt1)
< "*" Or arr(cnt1) < "/" Or arr(cnt1) < "^" Or arr(cnt1) < "." Then
GoTo eh
End If
wrdd = wrdd + arr(cnt1)
Next
Target.Value = "=" & wrdd
eh:
Application.EnableEvents = True
End Sub

what I want to do is if the user types 3+5 then excell will change 3+5 to
=3+5 and will solve the operation; the problem us that
target.value.words.count
and Target.Value.words(cnt1) dont exist in excel, any suggestion
thanks
