Can you link a text box to an incorrect answer on a true false quiz?

I am very new to adobe packages and our company has recently purchased captivate 7 so I can create e-learning packages. I had an hour training session to show me the basics from someone who has captivate 4. I am in the process of creating a package and what I want to be able to do is have a question slide with the option of a true/false answer but what I am struggling to do is if the person gets the answer wrong I want a text box to pop up to say incorrect then why it is incorrect (i.e. the reasoning behind it). Can you do this and if so how? Thanks, Laura
