Make sure hand isnt nil

[somber niche]

am i stupid but what do you mean by that it isnt nil

@crimson oar

[stark cape]

Error is happening because hand is nil sometimes

Nil means there is nothing

🟪 FindFirstChild finds nothing and returns "nil"

🟥 Then you try to clone nil aka nothing and you get an error

[crimson oar]
