Could someone fill me in on why I get an error using the following code for navigation...

// constructor for a quiz page object
function quizPage(src,time, timeLimit, tries, score, completed) {
  this.src = src
  this.time = (!time) ? 0 : time
  this.timeLimit = (!timeLimit) ? 0 : timeLimit
  this.tries = (!tries) ? 0 : tries
  this.score = (!score) ? 0 : score
  this.completed = (!completed) ? false : completed
}

// create array of all quiz pages in the entire quiz
var quiz = new Array()


quiz[0] = new quizPage("al_home.htm")
quiz[1] = new quizPage("al_q1.htm")
quiz[2] = new quizPage("al_q2.htm")
quiz[3] = new quizPage("al_q3.htm")
quiz[4] = new quizPage("al_q4.htm")
quiz[5] = new quizPage("al_q5.htm")
quiz[6] = new quizPage("al_q6.htm")
quiz[7] = new quizPage("al_q7.htm")
quiz = new quizPage("al_q8.htm")
quiz[9] = new quizPage("al_q9.htm")
quiz[10] = new quizPage("al_q10.htm")
quiz[11] = new quizPage("al_sum.htm")
quiz[12] = new quizPage("al_home.htm")


// navigate to next quiz page in sequence
function goNext() {
  var currPage, i
  for (i=0; i<(quiz.length-1); i++) {
    if (parent.main.location.href.indexOf(quiz[i].src) != -1) {
      parent.main.location.href = quiz[i+1].src
      break
    }
  }
}


Once I navigate using the next button to the al_sum.htm page, when I click next to go back to the al_home.htm page I get

parent.main.location.href is null or not an object

thoughts?

I tried location.href instead of parent.main.location.href, it works fine looping back to home and all the other pages in order.

Cheers!

It does not work on mine and I don't understand how it would without knowing which frame to target. Any other thoughts?

Can you do an alert on parent.main.location.href's value before and after the line

parent.main.location.href = quiz[i+1].src;

to get some clue on that.

Actually, I didnot try that with FRAMES. So I tested that for any flaws in the goNext function, and there wasn't any.

Cheers!

Also it would be better, if you could explain about which frame is showing what and its names, which frame contains NEXT button/link and onClick of that, which frames shows the next quiz, etc... so as to suggest you different options.
