difference between "raise 3bet" and "4bet"?

[Fingerswinger]

what is the difference between these two:

4Bet Preflop = (cnt_p_4bet / cnt_p_4bet_opp) * 100
Raise Preflop 3Bet = (cnt_p_3bet_def_action_raise / cnt_p_3bet_def_opp) * 100


or more specific, what is the difference between these two:

cnt_p_4bet
cnt_p_3bet_def_action_raise


thanks.

4-bet includes 4-bets, 5-bets, etc too.
