Hi,
Try:

In your example, in B2 put "=qwerty(a2)"

Function qwerty(ByVal rng As Range) As Double
qwerty = Evaluate(rng.Value)
End Function

A while back someone helped me write this code. Basicall someone inputs a
text string like '4+5 in cell A2 and in another cell you type =qwerty() and
the result is 9 (for the example given anyways). How do I change the formula
to accept a cell reference. For instance I want it to be =qwerty(F4) to look
at the text in F4.

Function qwerty()
Dim s As String
s = Cells(2, 1)
qwerty = Evaluate(s)
End Function
