Fridge problem

[RavenHart1]

I keep getting this error when i'm trying to open the fridge to pick back up the item i dropped in:

I just don't get whats wrong since i did not modify the script whatsoever ?!

line 507: table.insert(elements, {label = 'x' .. items[i].count .. ' ' .. items[i].label, value = items[i].name})

So i noticed that this happens when i add a new item to the fridge... Lets say that i put in water, bread and beer.. i restarted the server. i can take these 3 items in and out as i want... If i add a new items like tequila lets say... then i get this error and i can't access the ''get items '' menu anymore.. if i then restart its all good and so on ... :/

Can't figure out why the hell it's not working!! I really new help please :(
