  1. What do you want to achieve?
    I am trying to make like a dash system for example Rogue Lineage Dragon Sage Class one just to tell the module.
  2. What is the issue?
    So I was using @Quasiduck 's Lightning module, I’ve never used it before and I got this problem “ReplicatedStorage.Modules.LightningBolt:88: attempt to perform arithmetic (mul) on nil and number”
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I havent tried any solution yet since how I said its my first time using it and I have no clue what is causing the error.

Actually, ignore the post I fixed it, it was a random errow with NewSparks I tried to use LightningBolt.new with the LightningBolt Module
