Hi Bonnie,

Sorry to pester. I think I have solved the previous error by changing

>vr.Sort(MyArrayListSorter);

to

vr.Sort(new MyArrayListSorter());

The code is now going into your sorting routine, but then erroring on the line

s1 = s1.Substring(s1.Length() - 9);

with error text (128): 'string.Length' denotes a 'property' where a 'method' was expected

I'm afraid that I am now stumped again.
