I tried to make my own papyrus script for my mod, i had got a lot of mistakes but i fix lot of them (but not all of them) but i still have got a little small mistake here.
The error message is that: extraneous input '.' expecting ID
so, what does that mean and what did i should do?

It means you've written a full stop in a spot where the compiler was expecting an ID to be written. Check out the first number inside the brackets. That's the line in the script that the error can be found
