Im trying to have weapons require a safety function, script is below with attached Gyazo of the scripts location in the model.

C = script.Parent.Parent.Safety
local p = script.Parent:GetChildren()

function Toggle()
    if C.Value == true then
        open()
    elseif C.Value == false then
        close()
    end     
end

function open()
    for i = 1, #p do
        if p[i]:FindFirstChild("Flangs") then 
            p[i].Flangs.Transparency = 0
        end
    end
end

function close()
    for i = 1, #p do
        if p[i]:FindFirstChild("Flangs") then 
            p[i].Flangs.Transparency = 1
        end
    end

end

C.Changed:connect(Toggle)
