Seems to be a lot missing assumptions. Each given answer can be correct given different starting conditions.

Running the code as-is got me an error first (tblUsers does not exist. doh!).

I then created the table and got 0 rows as the result.

I added 1 row and got 1 row as the result.

Added another row and got 2 rows as the result.

Adding more rows kept the result at 2 rows.
