what's wrong with this coding?

Code:

CreateAmmoBox(pos, angle, team)
{
        block = spawn("script_model", pos, 1 );
        block setModel(level.crateModelBoobyTrapped);
	block Solid();
        block.angles = angle;
        block SetOwner( level );
        block thread AmmoBoxThink(team);
        wait 0.01;
}

Code:

AmmoBoxThink(team)
{
        while(1)
        {
                for(i = 0; i < level.players.size; i++)
                {
                        if(team != "all" && level.players[i].team != team){
                                continue;
                        }
                        if(DistanceSquared(self.origin, level.players[i].origin) <= Power(50, 2)){
                                level.players[i].hint = "Press ^3[{+activate}] ^7to Refill your ammo";
                                if(level.players[i] UseButtonPressed()){
                                        level.players[i] DisableWeapons();
                                        level.players[i].weaponlist = level.players[i] GetWeaponsList();
