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?

Have him say thing #1 - Then turn Self-switch A on.

In a second event page, have the condition set to self-switch A and have him say thing #2 in the second event page.
