#2

Which random?

chaaaaaaaaaars

#3

Make sure that theres atleast one object in the list

#4 
randomHat = bp:GetChildren()[math.random(#bp:GetChildren())]
randomitem = hats[math.random(#hats)]|

Can you try this?

#5

The reason this happens is because your list is empty. Make sure there are multiple objects inside it.
