dynamic panel estimation help

[berk]

I dont solve this in eviews Dynamic Panel Wizard example.
In example variables :The analysis fits the log of employment (N) to the log of the real wage (W), log of the capital stock (K), and the log of industry output (YS).
After in first step it writes: enter the list: w w(-1) k ys ys(-1)
so why there is no k (-1) and why the list includes variables and theirs (-1)
