First question... I think I made a mistake. You corrected it.

Second...
eg.
Selection.Formula = "=MyFunction(" & rngFirst.Address & ", " &
rngSecond.Address & ", " & rngThird.Address & ", " & rngFourth.Address & ")"

Rob,
Its Great.
Thank you for your patiance and taking me out of a major problem.
However there is a small problem.

If I use your code as it is the result is nothing.
If I replace If Err.Number < 0 to If Err.Number = 0 I get the proper
result.
Can you pl explain this or am I doing somthing wrong?

Secondly, How to use the same trick for the formula functions having
morethen one arguments? I have got a function which takes 4 arguments.
I am planning to use your solution for all my custom formula
functions.

With regards,
Malcom.
