My toolbox gun is not working! What do I do? Working in Player but not in Studio!

So i have a Item In the shop! It is doing what it is soposed to do, but the problem is that when it loads, the Words load, but none of the scripts of the gun load properly! The Code is Really long so im not going to put it here, but the Fisrt Script is a Script, it does the The purpose of the script is so that every gun in a game that uses this gun kit will share one Ignore_Model. That way, bullet trails, bullet holes, and other fake arms will be ignored by the gun which makes the bullets more likely to hit a charector Part, The Next one is a Local Script, it is WAY to long to paste, 3K Lines, This is the main script for the gun, It just does all of the Main Setting for the Gun, Again, the Gun is working on Studio, but not in PLayer, Ok there is 1 last thing, and its the Setting, the only thing that it does is take lots of the functions from the last one and used them to make the gun shoot and all, but this one is a moduel script! Is there anything i can do? ( I think that the Last Module script is the only thing that is wrong!) Its to long for me to paste, but is there anything that you can help me with? Should it not be a module script?
