Changing text dynamically

Options:1. Use 2 text blocks one with "Show details" and one with "Hide details". Hide one and show the other to start. When you Show Details, hide the first and show the second.2. Use an action to Change Contents of a text block. You first need to put "Hide details" text in a variable to use in the action to change contents. If you want to put it back to "Show details" you will need to load the variable with "Show details" and then change contents again. For an example of how changing the contents of a text block works, study the code created when using Page Numbering Tool under the Tools menu.
