The Dink Network

In the last year of highschool, everybody have to make a computer project. I started mine earlier, and, it's of course dink-related, and will be released here very soon(in a few weeks). Now I need some beta-testers. The only condition required for somebody to beta-test my project is to know DinkC.
That's why, I'll give you here a small script. Find 2 errors in it(they are 3, in total), mail me at cypryoprisa@gmail.com, and I'll send you the project:

void talk(void)
{
freeze(1);
freeze(&current_sprite);
choice_start()
set_title_color #
title_start();
What do you want?
title_end();
"Hello"
(&story = 7)"Where is the key"
"Nothing"
choice_end()

if(&result == 1)
{
say_stop("Hello",1);
say_stop("`4Hello Dink",&current_sprite);
return;
}

if(&result == 2)
{
say_stop("`4I don't know",&current_sprite);
return;
}

unfreeze(1);
unfreeze(&current_sprite);
}
