You are probably comparing two values such as if you were to compare a position and if you say something like this....

local torso = player.Character.Torso
if torso.Position >= Vector3.new(5,5,5) then
print("Wow...")
end

Now the code above will have an error stating that you're comparing two userdata values but, you could use magnitude for the above example.. So if that is your problem try using magnitude or some other method. Thank you for reading this answer. Hope it helped you out.

But I'm using table.sort(), I'm not comparing anything. lucas4114 607 — 8y

And in the table are int values, not Vector3s how would I use magnitude to compare that? lucas4114 607 — 8y

As you can see on the error, the problem is in Line 18
