Show text field depending on what is entered in another text field
I have a text field called Name. I have two other text fields called City1 and City2. If the word Chicago is entered into the Name text field, I want the City1 text field to be visible and the City2 text field to be hidden. If the word Detroit is entered into the Name text field, I want the City2 text field to be visible and the City1 text field to be hidden. Any help is greatly appreciated.
