You're welcome, Frank! Glad I could help. =0)

Although, I *do* wonder why you're binding an int to a string property in your BO. I would think that your BO property would be an int also.

If you want yours to start at 1, as you've shown below, or if you need a different numbering scheme for some reason, then you would have to explicitly define them as you did.
