A module that does not produce grades should return NULL rather than an array in the function modulename_grades. So in your case you need:
function shelf_grades($shelfid) {
/// shelf does not generate grades
return NULL;
}
in your lib.php file
Hi Gustav,

- Where should the above code be placed in the "lib.php" file?
- What section of code should be replaced with the above code?

Hi WP1, I didn't see your question until right now. The code should replace the current code for that function in lib.php.
