Dynamic Text Box Not Updating

Hi, I'm from an actionscript background and only just getting to grips with Animate with HTML5 Canvas

I'm creating a simple maths quiz and having a problem displaying the updated score inside a dynamic text box.

I know the score variable is adding +1 (I'm using alert(score) to test this) but it isn't updating inside the dynamic text box (named countText in the properties panel).

Any pointers in the right direction would be appreciated.

Example code:

// check the question count

function scoreCheck() {

score++;

alert(score);

this.countText = score;     //  this textfeld is not updating

}

Hi thekay

do it so:

function scoreCheck() {
    score++;
    console.log(score); // tip: use console instead of alert
    this.countText.text = score; // add property text
}

    Just to add to the above.

    I know it's obvious but remember to declare the variable score (for a global variable put in the Global:Script part in the Actions panel).

    Also if using this. in the function then use .bind(this) in the event listener.

    e.g.    this.plusBtn.on("click",scoreCheck.bind(this));

    plusBtn is just something I made up as a button instance.

    Hopefully we have helped.

    Cheers.

          Thanks to everyone who has replied.

          Using the example provided by 'redesign' I have got the hang of it
