The Dink Network

I have a problem with my script:
void talk(void)
{
if (&sstein == 0)
{
freeze(1);
freeze(&current_sprite);
say_stop("!", 1);
say_stop("`7Dink!", &current_sprite);
say_stop("Mr. SmileStein what are you doing here?!", 1);
say_stop("`7Well i moved from Stonebrook to here.", &current_sprite);
say_stop("Oh and where's Libby?", 1);
say_stop("`7Erm...She's outside.", &current_sprite);
say_stop("...", 1);
say_stop("I don't belive you!", 1);
say_Stop("I was near your new house cause i escaped from goblins!", 1);
say_stop("And i could see Libby!", 1);
say_stop("`7Ok you got me.", &current_sprite);
say_stop("Then tell me where she is!", 1);
sp_dir(&current_sprite, 8);
playmidi("sadness.mid");
wait(750);
say_stop("`7She stayed at Stonebrook", &current_sprite);
say_stop("`7I didn't moved here but i escaped.", &current_sprite);
say_stop("WHAT?!", 1);
say_stop("`7I didn't know what should i do.", &current_sprite);
say_stop("`7The earth is dark and evil.I telled her to go with me.", &current_sprite);
wait(750);
say_stop("`7But she refused.", &current_sprite);
playmidi("4.mid");
wait(500);
say_stop("`7Dink.You must go back to Stonebrook and save the Libby and the world.", &current_sprite);
say_stop("Ok.I'll do it.Probably Seth tok her as a slave.", 1);
say_stop("I'll go back and i kill that motherducker once and for all!", 1);
say_stop("`7Good one Dink!", &current_sprite);
wait(750);
say_stop("`7But i have a bad news.", &current_sprite);
wait(500);
say_stop("`7The road to the Stonebrook is blocked.", &current_sprite);
say_stop("So how can i get there now?", 1);
say_stop("`7I don't know.Maybe villagers will help you.", &current_sprite);
say_stop("`7Oh and if you have a problem i'll try to help you.", &current_sprite);
say_stop("Allright.", 1);
unfreeze(1);
unfreeze(&current_sprite);
&sstein = 1
}
if (&sstein == 1)
{
freeze(1);
freeze(&current_sprite);
choice_start()
set_y(240);
set_title_color 7
title_start();
Need a help...Dink?
title_end();
"No"
choice_end()

if (&result == 1)
{
unfreeze(1);
unfreeze(&current_sprite);
}
}
}
When i tested there are two options to choose.One without words second with "No" word.When i select "No" i can't move but when i select the invisible one i can move!What should i do?
