1 script reference for 10 models (StringValue)?

I've been trying to reference my module script to 10 models instead add or modify the code lines in 10 models, just once with my module script?? I've been seeking for info on google, nothing really great resourceful to correct my mistakes

I know this is repetitive, perhaps I am beginner scripter as well.

local module = {}
for _,v in pairs(folder:GetChildren()) do
local model = v

local pos = model.PositionColor
local job = model.TitleColor
local jobrank = model.RankColor

EITHER OR

--[[local pos = game.Workspace.FirstLevelSet.PositionColor
local job = game.Workspace.FirstLevelSet.PositionColor
local jobrank = game.Workspace.FirstLevelSet.TitleColor]]--


pos.Changed:connect(function() -- Worker

end
end)

return module

If you are trying to shorten you're code, use dictionaries. I put an example below.

--Find Level and gold by StringRank
RankDict = {
	['Peasant'] = {1, 50},
	['Artisan'] = {2, 100},
	['Lord'] = {3, 250},
	['Shogun'] = {4, 500},
	['Monarch'] = {5, 1000}
}

local strRank = 'Peasant'
local Level = RankDict[strRank][1]
local gold = RankDict[strRank][2]

Hope this helps!
