Modulescript not working

[ChaosTheDwprived (Chaos)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I want to make an exposion with my custom modulescript but it doesnt reconize the first parameter.

2. What is the issue? Include screenshots / videos if possible!
   Im trying to create an explosion but it doesnt know size is a parameter, even if i put size in it still thinks its pos.
   
   

   

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   My friend put a holder parameter as the first parameter and it works.

You defined the function with a dot but are calling it with a colon.
ModuleScript.Method =/= Module:Method
