Javascript running twice

Hello, can someone enlighten me in this...I made it work... but somehow javascript is running twice each question, I can't seem to point where the failure is, ... console does not really show any log of activity while this happens, hope someone can help out, thanks

function print(message) { document.write(message); }

var questionarie = [ ["Alexander? " , "the great"], ["Devils number? ", "666"], ["First Code language? ", "javascript"], ["Favorite fight style? ", "krav"],


var score = 0; function action(questions){ for (var i = 0; i < questions.length; i+=1) { prompt(questions[i][0]) if (prompt(questions[i][0]) === questions[i][1]) { alert("you're right"); var htmlp = "You had question " + questions[i][0] + " correct" + "<br>"; score += 1; print(htmlp); }else { alert("you're incorrect"); } } }

action(questionarie); alert("you had " + score + "answers correct") document.write("you had " + score + "answers correct")

You are prompting twice in your loop:

if (prompt(questions[i][0]) === questions[i][1]){

You can either assign the result of the prompt to a variable and compare that to questions[i][1] or just delete the first prompt.
