// Change
setarray(.crafting_recipe_p1_t2_products, 40101, 1,40102, 1,40103, 1,40104, 1,40105, 1);
// to
setarray(.crafting_recipe_p1_t2_products, 40101, 40102, 40103, 40104, 40105);
setarray(.crafting_recipe_p1_t2_amounts,  1,  1, 1, 1, 1);

// To handout 1 random item you do it like this:
.@item_index = rand(getarraysize(.crafting_recipe_p1_t2_products));
getitem(.crafting_recipe_p1_t2_products[.@item_index], .crafting_recipe_p1_t2_amounts[.@item_ind//sex]);

// To handout all items you do it like this:
for(.@i = 0; .@i < getarraysize(.crafting_recipe_p1_t2_products); .@i++) {
	getitem(.crafting_recipe_p1_t2_products[.@i], .crafting_recipe_p1_t2_amounts[.@i]);
}
