Custom Gui crafting block but when you place the item and get the output the items used to craft dont disappear

So i created a custom Gui and i'm fairly new to Mcreator but i can get the output. but the problem is i cant get the items from slot 0 and 1 to disappear once they have been used to make the item in slot 2. so i am getting an infinite output 

here is a picture of my code so far
