I could use some help from the assembled wisdom here.
I understand how what is visible in the "hover" boxes is edited. I have no problem adding fields from the associated records onto hover details. However I cannot get related lists information to show up in the hover boxes. I have selected the checkboxes I want displayed (in this case say it's Activities), along with the checkboxes inside "Activities," and "Activities" is still visible and on the page layout as a related list, and yet they don't show up in the hover boxes.
Is there something I am doing wrong? I literally walked through the SalesForce provided help file step-by-step and I can't figure out why they won't work.
Help!
