I'm trying to make a randomized height system but it just wont work?

ive tried many things using 2 scripts using values in a stat folder it doesnt save

i have no clue whats happening hopefully you can help

local DataStore = game:GetService("DataStoreService"):GetDataStore("heght")
local DataStorez = game:GetService("DataStoreService"):GetDataStore("heght2")
local DataStorezz = game:GetService("DataStoreService"):GetDataStore("heght3")
local DataStorezzz = game:GetService("DataStoreService"):GetDataStore("stat")


local DataStoreh = game:GetService("DataStoreService"):GetDataStore("tewl")
