Zebedee, I'm going to go ahead and fix your link for you, but here's how you do it:

Type this:

{bitem:1896162}

and it will look like this:

Invalid Item  This item number is not valid. #1896162 by Not Available.

Also, the 15-minute guideline is just a minimum. You can work as long as you like or need on the assignments.

Regards,
Michelle
