@jeannem,
Welcome to A2K, Jeannem. Since you were able to post your question, it appears the activation process worked.
If memory serves me correctly from the last time I started a new account here, the activation link in the email automatically completes the process when you click on the link. There is no need to enter a number.
If I'm off the mark as to what your question is, could you clarify it a bit please?
