Dynamic Page Problems!

Hello. I am trying to create a dynamic page but when I do the Preview Panel does not appear on the page. Also, back on the database page I am unable to ‘Edit Live Database’. Probably doing something foolish as I am only a beginner! Please help.

Edit of live database does not seem to work, edit in Sandbox and Sync to live for now.

I am not sure what you are trying to accomplish on your dynamic page. Can you screenshot it maybe?
