Word 2007 Options

Hello,

I am not an expert with Word 2007. Any assistance would be appreciated.

I am trying to create a document that will change based on a dropdown selection.

If the dropdown is "option 1" it will show only a specific part of the document, and if "option 2" is selected, then it will show other parts of the document.

I know how to hide text, but I can't seem to get the text to show up again.

Thank you for taking the time to read and provide suggestions.
Josh
