Sorting numbers
 

I am having difficulty when attempting to do a numbers descending sort, from
a position where the data is in rows.
I have no trouble with other sorts of this type, but in this particular
sort, a six digit number is sorted behind a five digit number, because the
first digit is smaller than the first digit of the five figure number.
Any help please?
- Also how do I avoid getting the title headings (shown in the left column,
in the row alignment) unnecessarily involved in the sort?

Thanks in advance
