Argument 1 missing or nil error on roblox studio
Sophia Terry 
Hope you are having a good day. I am just here to say I have watched Alvinblox's egg hatching system tutorial and I am currently at part 2. There is a new error called "Argument 1 missing or nil" it is at line 60 in the petFollowPlayer script (local pet = game.ReplicatedStorage.HatchablePets:FindFirstChild(petName)) here is the code

Looking at the line local pet = game.ReplicatedStorage.HatchablePets:FindFirstChild(petName)
The error is telling you that, for some reason, petName isn't defined. So looking at how the variable is defined, we need to check how game.ReplicatedStorage.equipPet is called. So looking in the addToFrame local function, you call it like this : game.ReplicatedStorage.equipPet:FireServer(). Your problem is that you haven't provided the pet name at all. So just do the same thing you did with the unequipPet event.
buttonConnection[#buttonConnection+1] = newTemplate.MouseButton1Click:Connect(function() if newTemplate.Equiped.Text == "EQUIPPED" then game.ReplicatedStorage.unequipPet:FireServer(pet.Name) newTemplate.Equiped.Text = "UNEQUIPPED" newTemplate.Equiped.TextColor3 = Color3.fromRGB(255,0,0) else game.ReplicatedStorage.equipPet:FireServer(pet.Name) setTemplateEquipped(newTemplate) end end)
