I get an error that says Size is a UserData value.
for loop = 1, 15 do wait(0.5) script.Parent.Size = script.Parent.Size + NumberSequence.new(1) end
You can't add a vector3 and a numbersequence up. If you want to change the size of the brick constantly, you can use something like this:
local addSize = Vector3.new(0,1,0) --this is the amount it will resize. for loop = 1, 15 do wait(0.5) script.Parent.Size = script.Parent.Size + addSize end
Hope this helps!
