Hi sages,

Just for having weekend fun. Let's for simplicity have a UDF with two
variant/ranges arguments. If the dimension of the second (distant) one
differs from that of the first, calculation error in the function should be
trapped and therefore registered by means of MsgBox. In the moment, however,
when a user tries to select the second of range-inputs by dragging, even
pointing at the first cell of this range is immediately accepted and, due to
trapped error messages, the input obstinately fails. With difficulties two
cells can be selected at once but nothing more. The user must shift the
"dragging" selection to upper input line or type down the whole range address
in the input box manually. How would a professional (especially the most
valuable one) build the macro so that the UDF would be more user friendly?

For elucidation of the problem:

Function RangesDifferent(A, B) As Boolean
If A.Count < B.Count Then
MsgBox "Dimensions of ranges differ"
RangesDifferent = True
End If
End Function

With all regards and thanks

My guess: a professional would not use MsgBox in a UDF. The purpose of a UDF
is to return a value to a cell. Subroutines are used for all other purposes.
best wishes

Are you calling the function from a worksheet cell or from withi
another procedure? Calling the function from a worksheet cell,
couldn't recreate the problem

Thanks for both remarks. First, you soothed my conscience: there is not a
gimmick I could have passed. Second, you diverted my way from excessive ca
I in fact fully realized that quite similar Slope and Intercept do not
hesitate to return only #N/A in analogous situation.
Best wishes for next useful answers to some screwy questions. Pity the
number exponentially rises, so even the gems of replies are mostly lost.
