I am testing Gradebook on Moodle 2.0 and, for some reason, I can't assign ID numbers to my grade items, every time I try do it, I get one of those:
"Coding error detected, it must be fixed by a programmer: Url parameters values can not be arrays!"
As a consequence of not being able to assign those IDs, I can't create any custom calculations, of course.
This is the page where I am trying to assign the IDs.
