add bonus score only once?

guilleface

hey guys i need help with this, i have a score set like this, when score is less than 99 i add a bonus 100$, when score is greater that 100 and less than 499 to add a bonus of $200 and when score is greater than 500 to add a bonus of $300, but if the player replays the level he gets another bonus again and i only want to give the maximum of certain amount, also if its possible like say player first time made a score of 80 so he gets $100 bonus so on second try he makes 300 points but since he already got 100$ from first time he should only get 100$ more instead of $200, i hope i explain good.

thanks tshirtbooth but i already watch that video but is not helping if the player restar the levels it will still add extra lives because i have to change game score to 0, say i set to add a live at 30000 points, so thats sit i dont want the player to get another live if he replays the level and gets another 30000 points again.
