hi,
In the code below count_down() function is called when a question pop-up. If the correct answer is selected the timer should disappear (or) if the timer is (0:00) it should disappear(i.e., count_down should stop).





//////timer//////////
string time_str;
string temp_str;
var seconds = 30; // number of seconds to be counted down
var temp_seconds;

function count_down()
{
while(seconds > 0)
{
sleep (1);
seconds -= 1;
temp = int(seconds / 60); // compute the number of minutes
str_for_num(time_str, temp);
str_cat (time_str, " : ");
temp_seconds = seconds - temp * 60; // compute the remainder (the number of sec)
str_for_num(temp_str, temp_seconds);
if (temp_seconds < 10)
{
str_cat (time_str, "0"); // add a zero (if needed)
}
str_cat (time_str, temp_str);
}
}

///////////////////quiz
function give_quiz1()
{
current_quiz = 2;
toggle_quiz_panels(1);

count_down();

if(current_quiz==2)
{
str_cpy(quiz_string, quiz2_string);
str_cpy(answerA_string, answer2_optionA_string);
str_cpy(answerB_string, answer2_optionB_string);
str_cpy(answerC_string, answer2_optionC_string);
str_cpy(answerD_string, answer2_optionD_string);


this_answer_is_correct=1;
}

}


function answer_quizA()
{
answer_quiz(1);


}
function answer_quizB()
{
answer_quiz(2);

}

function answer_quizC()
{
answer_quiz(3);

}
function answer_quizD()
{
answer_quiz(4);

}


function answer_quiz(answer)
{
player_var = answer;

if(answer == this_answer_is_correct)
{
str_cpy(response_string, "C O R R E C T ! Well done");

snd_play (correct_answer_wav, 200, 0); //play select sound


}
else
{
str_cpy(response_string, "Sorry, you got this one wrong.");

snd_play (wrong_answer_wav, 200, 0); //play select sound
}
wait(2);
quiz_text.visible= off;
toggle_quiz_panels(0);
quiz_panel.visible = on;
response_text.visible = on;
sleep(1);
toggle_quiz_panels(0);
