Importing Variables from Another Mod

I'm currently working on an addon for a mod that will trigger a variable when the player right clicks an item, and when I import the other mod's variables into my procedure, I get an error stating: error: package net.mcreator.ghostriderbyyofadda.network does not exist and error: package GhostriderByYofaddaModVariables does not exist

I'm not sure if I'm doing something wrong but here was the code for my procedure: https://pastebin.com/Cpc2scXG
