attempt to index global 'cBlue' (a nil value)?

Why does it say that cBlue doesn't exist in StartGUI?

local Blue = script.Parent.cBlue
local Green = script.Parent.cGreen
local Pink = script.Parent.cPink
local Red = script.Parent.cRed
local Yellow = script.Parent.cYellow
local Random = script.Parent.cRandom
