What's really odd is only the first loop works. I'm thinking register_globals here. In every example you've posted, you've used $last_name and $_SESSION['last_name'] -- but these are the same thing if register_globals is on, and would lead to your posted output with the single characters on the 2nd iteration and nothing after that! At least one posted suggestion used $first and $last rather than $first_name and $last_name -- did you actually try with the shorter names, or stick with your longer matching ones? Cheers!
