Asma,

You may have specified more levels in your experiment than 4 - in this
code, For i = 0 to 1 means that the loop will run twice (to add 2
unsampled itmes to the 2 sampled itmes in ratelist). If you want 6
unsampled itmes then you use For i = 0 to 5, for example, otherwise
you will get a Level specified is not valid error. Also, make sure
that there are sufficient levels in ratelist to accomodate these items
otherwise you will get the same error.
