Just to add to Rod's proposition: if you are on Captivate 6 or later, be sure to group the Text Containers, that makes it a lot easier to hide all of them and you'll need less editing work for the duplicate advanced actions. And if you are on CP7 you can use shared actions within the same project as well. The standard advanced action needed for each 'click box' will look like this:
Hide Gr_Texts where Gr_Texts is the object group with all text containers
Show TC_xxx where TC_xxx is the text container to be made visible for that click box, only this label has to be edited in the duplicate actions; sequence is important, first hide, then show
An extra advantage is that the play head will not be released by a standard action, which is the case if you would use a simple action:

PS: this is a rather simple case, you really don't need an 'expert' at all for that.
