Editing intro speech, need help

[ManyThousands]

I'm working on a pokeemerald hack, and I've been editing Birch's intro speech, but even though I've changed the line under gtext_Birch_Pokemon, he still says "this is what we call a pokemon" while sending out lotad. Does the line exist somewhere else too, which could be causing it to default to the original dialogue?

I've looked elsewhere and I can't find any solutions, so it might be something I did to mess it up, which I wouldn't doubt :s

EDIT: Nevermind, I got it! Turns out the text line I was looking for was in 'strings.c'. Expect me back soon, asking for help with another equally goofy problem.
