Weird coding errors?

[SwingsDarkCreeps]

hi, so this: //(double slash)- corresponds at commentaries inside the script(like 7he Dubz
said before);
{}(brackets)-corresponds at function branch or
offshoot (like Mugbill said before);
A functions usually start with a bracket and end with another bracket(exceptions if you don't use break function) like this:
void TheSpecificCallbackFunction(...)
{
here you write the code;
}

that is the general structure of a function;
