I am VERY new to salesforce.I feel like I have moved to a foreign county and trying to learn the language (without a translator). We are using a program (App) that has pre-developed "Custom Object" (tabs). On the bottom of one of the objects I need to able to enter activities. (1) When I go into Create/Object/Custom Objects I can see the object. When I click on edit, "Allow activities" is checked. (2) When I select the object and go to Page Layout, I see three sections at the bottom (a) Open activities (b) notes and attachments and (c) activity history.
When I open the tab, none of those appear. None of those sections are visible. What am I doing wrong. Help
