I don't know what's wrong with this script. When I speak to this lady the game freezes:

//script for xanthara, the owner of the medical lab

void main();
{
int &ransay = random(3,1);
if (&ransay == 1)
{
say("`4Good day to you sir!",&current_sprite);
}
if (ransay == 2)
{
say("`4Intreted in biology, are you?",&current_sprite);
}
if (ransay == 3)
{
say("`4Come in my dear sir!",&current_sprite);
}
}

//talk procdure
void talk();
{
//freeze 'em
freeze(1);
freeze(&current_sprite);
//blablabla
choice_start()
set_y 240
title_start();
Welcome, my dear sir into this lab.
title_end();

(&dragon == 2)""Here's the corpse of the dragon"
"What is this place?"
"Do you need help"
"What corpses are these?"
"Goodbye"
choice_end();

//if &dragon and &slayer are 2
if (&result == 1)

}

}
