rpg gaming script modification help

[PJ droopy pants]

I am trying to change the code in my script to make it where the users experience points reset back at 0 each time the user levels instead of the experience point accumulating like it does now. I am doing this because I am adding a status bar that shows percent to next level and the way it is now it starts at around 80% after lvl 2. Thank you for any help you can offer and I will post the code that I have.

 

//level 2 - 500

//level 3 - 1500

//level 4 - 3500

//level 5 - 6000

function experience($L) {

  $a=0;

  $end=0;

  for($x=1; $x<$L; $x++) {

    $a += floor($x+1500*pow(4, ($x/7)));

  }

  return floor($a/4);

}

function Get_The_Level($exp) {

  $a=0;

  $end =0;

  for($x=1; ($end==0 && $x<100); $x++) {

    $a += floor($x+1500*pow(4, ($x/7)));

    if ($exp >= floor($a/4)){

} else {

  return $x;

  $end=1;

}

  }

}

function Get_Max_Exp($L){

$end=0;

if ($exp == 0){

return 457;

$end =1;

  }

for($L=1;($L<100 && $end==0);$L++) {

  $exp = experience($L);

  //echo $exp;

  if ($exp >= $user_class->exp){

	return $exp;

	$end=1;

  }

}

}

.

Why not take the total of the lvls below the one the player is on at the current time. Then use that and the expirience points needed for the uncompleated lvl to find the percentage?

That is what it is doing now. For example, when a users reaches the lvl 4 threashold the have 3500/3500 experiance points and that is 100% then it lvls them up to lvl 5 with this result 3500/6000. So the satus bar shows 58% to next lvl. I would like that to be 0%. So i was trying to figure out how to reset the exp back to 0 when lvl is reached. So it would be 0/2500 to lvl 5.
