Hey, I was wondering if a local script created Integer Values for a local player, then an a non-local script have access to those Integer Values?
If FilteringEnabled is off, then yes, under most conditions (Local parts being the exception).
If FilteringEnabled is on (which is the general recommendation from a security standpoint), LocalScript's cannot produce any instances which a global script can read.
Any communication then must be done using BindableFunctions and similar objects. These let you build functions which normal Script objects run, but that LocalScripts can call to safely perform actions.
