How do I correct this script? {UNANSWERED} [PLEASE ANSWER]

Using commas in that way makes a tuple. red will only be given the first thing in the tuple.

This is not an appropriate case for a tuple.

It doesn't really make sense for a variable to simultaneously "be" all of those things (what would that mean? What do you do if you want to do math on such a thing? How do you separate the values later?)

You likely want a list of objects:

local frame = workspace.Frame4
local parts = { frame.Part1, frame.Part4, frame.Part7, Frame.Part10, Frame.Part13 }
-- Curly braces. An entirely different thing.

parts is now a list. Changing parts (the list) won't mean anything -- a list doesn't have a color, for instance.

If you want to change all of their colors, that means you change the color of each, using a loop:

function changeColor( list, color)
	for _, element in pairs(list) do
		element.BrickColor = color
	end	
end

while true do
	changeColors( parts, BrickColor.White() )
	wait(0.1)
	changeColors( parts, BrickColor.Green() )
	wait(0.1)
	changeColors( parts, BrickColor.Red() )
	wait(0.1)
end

Ideally you would not list all of the parts in the definition of parts and instead would group them into a model. Then you could simply say parts = frame.Model:GetChildren().
