Iron golem loot table

I want to make that if the player kills an iron golem it  drops between 3 and 5 iron ingots and if it is not killed by a player it drops between 1 and 3. I already done it, but i dont know why it doesnt work. When it is killed by something that it´s not a player it always drop only 1 iron ingot. I leave you my code so if someone can tell me what is wrong
