I need a function that, given a range (single cell) as an argument, will
determine if the cell has been conditionally formatted with EquationIs and,
if yes, return the first formula as a text string.  I tried:

Function mnb(r As Range) As String
mnb = r.FormatConditions(1).Formula1
End Function

This almost works, but it returns equations with cell references translated
to the location of the function call rather than the range in the call.  For
example, if the conditional formatting in C1 is formula =(C1>10) then
=mnb(C1) should display =(C1>10), instead it is displaying =(Z100>10) if
=mnb(C1) happens to be in Z100.

As a sub there is no problem:

Sub macro3()
Dim r As Range
Dim s As String
Set r = Selection
s = r.FormatConditions(1).Formula1
MsgBox (s)
End Sub

Thanks in Advance
