Firstly: Use [ pawn] your code [/ pawn] (without the spaces ofc).
Secondly:The "nested comment" warnings appear due to something like this:

Код:

/* Hello

/* I am answering a question.    <-----------This is a nested comment.

*/


Then somewhere you have */

While the proper format is

Код:

/* hello */
/*I am answerig a question.*/

And for the errors, you need to show the code so that I can see where the errors are. By the looks of it, it seems you put an extra bracket somewhere.

And for "symbol never used" warning, well, you have to use the symbol you have declared.
