I did, and it did. The main reason I was asking, was in case there was something wrong with doing it that way - just because it seems to work, doesn't mean it's "right", so I wanted to make sure I wasn't doing something wrong...

As for your question about the handling of the different formatting of the names - that shouldn't be an issue, as the source of these data he's using is a database where the data will be consistent for each user ID.
