[Shroomed]

Can you tell me whats wrong with this level up system for my new server?

// NPC made by nervNAT
if (playerenters) {
if (!hasweapon(*System)) {
toweapons *System;
setstring client.maxmp,#v(int(strtofloat(#s(client.level))*1 .5));
setstring client.maxhp,#v(int(strtofloat(#s(client.level))*1 .8));
setstring client.hp,#s(client.maxhp);
setstring client.mp,#s(client.maxmp);
setstring client.maxexp,1000000;
setstring client.level,1;
}
this.baddiecount=compuscount;
timeout=.05;
}
if (timeout) {
if (playerhearts<playerfullhearts) setstring client.hp,#v(strtofloat(#s(client.hp))-1);
setstring client.exptonext,#v(strtofloat(#s(client.level))*5 );
baddycheck();
playerhearts=playerfullhearts;
if (strtofloat(#s(client.hp))>strtofloat(#s(client.ma xhp))) setstring client.hp,#s(client.maxhp);
if (strtofloat(#s(client.mp))>strtofloat(#s(client.ma xmp))) setstring client.mp,#s(client.maxmp);

}
function baddycheck() {

}}
function dead() {

}
function exp() {

}
}
