So let me see if I got this right. You have a left column which contains a bunch of checkboxes. A right column with divs to display content. When a checkbox is checked/unchecked you want the content div on the right to update and reflect what's been chosen. Is that all or is there a database update in between those two steps?
Let me know if I'm understanding this right. If I am we'll just add an onClick event to the checkboxes to fire a js function to update the div content (innerHTML). Let me know, cheers.
