Advance Action Help

I am working on a project where I have a hot spot on the screen.  When you click on the hot spot a text box opens. I am looking to set it up where when the learner closes the text box, the next hot spot will appear.  I know it has to do with advance actions and conditional tabs and variables. Can anyone please help. Thanks.

Rollover Text box

I am trying to set up some rollover captions for a project but I want to change the text box color.  Is there a way to do this?
