I have tried so hard with this script! Only to be extremely frustrated! Please help!

VOID MAIN(VOID)
{
sp_base_walk(&current_sprite, 340);
sp_speed(&current_sprite, 1);
return;
}

VOID TALK(VOID)
{
if(&plant == 0)
{
freeze(1);
choice_start()
"Blah?"
"Return"
choice_end()

if(&choice == 1)
{
say_stop("blah",1);

wait(500);
say_stop("Well gotta go, Ramen!",1);
wait(500);
say_stop("`2Bye",&current_sprite);
unfreeze(1);
return;
}
if(&plant == 1)
{
freeze(1);
choice_start()
"Do you know where I can find a water-can?"
"You people sure are brutal, killing a pillbug so slowly with a rock..."
choice_end()
if(&choice == 1)
{
say_stop("blah",&current_sprite);
wait(2000);
say_stop("OK! You really don't need to tell me any more!",1);
wait(2000);
say_stop("`2say",&current_sprite);
unfreeze(1);
return;
}
if(&choice == 2)
{
say_stop("It fun! You want to try?",&current_sprite);
choice_start()
"Yah!"
"Are you inhumane??"
choice_end()

if(&choice == 1)
{
say_stop("Good! Me take you to kill fields!",&current_sprite);
}
}
}
}

I can see the first choice screeen but it just freezes when I answer.
