Automatic forwarding to next page from matrix

Hi,

I am trying to automatically forward to the next page in my survey (without having to click the next button).
I know the Javascript code for this is usually:

Qualtrics.SurveyEngine.addOnReady(function()
{
var that = this;
var answers = $$(".SingleAnswer");
for(var x = 0; x<answers.length;x++){
answers[x].observe('click', function(event) {
that.clickNextButton();
});
}
});

This works perfectly fine with single questions, but not with a matrix.
Anyone can help me out?

So just to be clear: Final question on the page that would include the code is a matrix (so multiple questions combined).

Thanks a lot!
