Why does this error seem to happen?

[TafareWoomy (picklepicolo)]

I created a code whereas the player can spawn in a type of accesory and script put inside their character model on them with the click of a button, then when the button is pressed while that accesory is on them and the script is inside their character model, i want them both to be destroyed but instead i get this error

this is the server script for it

and this is where the scripts and accesory come from in replicated storage

You passed an Instance to FindFirstChild however FindFirstChild expects a string.

Instead of

local bike = char:FindFirstChild(ChosenCart)

try

local bike = char:FindFirstChild(ChosenCart.Name)

same goes for the ChosenAbility as well:

local ability = char:FindFirstChild(ChosenAbility.Name)

The script works now thanks to your advice
