The challenge was a long time ago.
I believe that there are a few posts on the subject. You can try searching.

I know that one solution had code and instructions on how to use it and it worked.

try looking at the following I don't know if it uses the same approach as the code you cite.

Thanks Dave for the reply, I used this as well and this works fine up to 50 amounts, but this code does not work if amounts are more than 100 and most of the times excel gets freeze when I run the code.
