How Do We Make Our Solution Work?

All the previous efforts did not allow my changes to lock in. as soon as I hit "update" they vanished....
I am stuck and we cannot deliver our courses as promised.

We have created a mock up of what we want our clients to see anytime they login. Please see the attached. I also attached our simple log in page

Bottom line; How do I create this? I must be missing something, because when I try to follow the instructions in the manual, I am not able to do this...

Are we using the right plug in? Is there an easy way I am not seeing?
I appreciate your help
