Hi,

Would you care to explain what you mean by "3 combination 5"

I meant 5C3. That is the number of possioble way of choosing 3 letter from a group of 5 letters.

What code or logic do you have so far?

In Excel you can use COMBIN().
The formula is n!/k!(n-k)!

Wow, that was fast, for having "none" a mere 8 minutes ago! ;-)

So what is the problem with the this code?
