Item Reward depends on chances

[Reborn]

Hello everyone. Can anyone help me make this script?

What I need to do is this.

The player will require item ID 501 for them to play this npc.

setarray .itemReward[0], ItemID, ItemChance, ...

setarray .itemReward[0],501,10,502,20,503,30,504,40,505,50;

The player will get one item reward depending on the chances that they will get. Rare item will have small chance only.

prontera,156,187,2	script	Valkyrie#1	4_F_LGTGIRL,{

	if (countitem(501) >= 1) {
		delitem 501,1;
		@chancezz = rand(1, 100);
		mes "ok lets see";
		
	if (@chancezz <= 50) {
		mes "You got the common prize!";
		getitem 501, 2;
		close;
		end;
		}
	if (@chancezz >= 80) {
		mes "You got the rare prize!";
		getitem 501, 12;
		close;
		end;
		}	
	if (@chancezz >= 51) {
		mes "You got the uncommon prize!";
		getitem 501, 5;
		close;
		end;
		}			

		
		}
	mes "Sorry no potions, no items";
	close;
	end;

}

Well i tried my best 

It works at least

@AnnieRuru Made a fantastic post with three excellent ways on how to do this already...
