Excellent, I did not know ISNUMBER existed, I never needed it before,
but for my usage I would remove the word "Non-numeric" and just leave ""
so the cell would remain blank.
I can see that in LO or any other spreadsheet that treats Letters as
Numbers, this would be a necessary function.
I have learned something today - thanks

Hi all, this is a little example to show what is going on.
In A column I have a numeric list from 1 to 21, in the middle I have a
letter, lets put A.
If a run this function in the next column =IF(A1>10), this function
evaluate the letter A like TRUE, why?
1 FALSE
2 FALSE
3 FALSE
4 FALSE
5 FALSE
6 FALSE
7 FALSE
8 FALSE
9 FALSE
10 FALSE
11 TRUE
A TRUE
13 TRUE
14 TRUE
15 TRUE
16 TRUE
17 TRUE
18 TRUE
19 TRUE
20 TRUE
21 TRUE
The ODF1.2 spec says ("functions" are here the comparison operators),
"These functions return one of True, False, or an Error if Left and
Right have different types, but it is implementation-defined which of
these results will be returned when the types differ."
And OpenOffice.org and LibreOffice have the simple rule "number is less
than string". Excel and Gnumeric have these results too.
Kind regards
Regina
