Weird coding errors?

[7heDubz]

For debugging your own code you can take the error code and find the corresponding (12,36) (line, character) is you get a line and a 0 for example, (12,0), try checking the line of code before it the one it returned with.

But yeah, you were way mistaken, the double forward slash is used for commenting lines of code. Brackets contain groupings of code such as the kind you find in a function.
