Having Trouble with a conversation event

I am new to Ace and I am having trouble figuring out how to get my King character to say different things. For example he tells the characters what they need to do next in the story and then when the event is over the only thing that I want him to say is "Go forth young warriors and defeat the Demon King." However, when I use switches and another event page my options are have him only say one thing or the other. What am I doing wrong.

You can assign up to 4 self-switches and add many pages to the event.

Use the initial text as you do and end it with turning self-switch A on, the second page will have self-switch A ON as condition, that page will end with self-switch B being turned on, which is the condition for page 3...and so on..easier than setting external switches or variables.

If he gives you a quest, you'd probably want to use a regular switch rather than a self switch, because there will probably be other things that will change once you have the quest (you couldn't do something before, but now you can). Self switches are for when you only want that one event to change. Switches are for when you want several events to change after something happens.
