Problem : 22:54:45.165 - SadBlade is not a valid member of Model

Where do you define/explain what/where SadBlade is? SadBlade is basically returning nil because it is not there. You can try to use a FindFirstChild() method or the WaitForChild() event to essentially see/wait for the child to be added.
