Your code is non-trivial, so I'm not going to try to get it setup and working on my side. Instead, I'd suggest adding a Watch Window, and check the results. That should help you isolate the issue and quickly resolve it.

Although error messages are sometimes misleading, it really should help you figure it out, or get close enough to post back with very specific information about what's going on there.
