Hello,

I have a image that loads on a button click. The image is quite big and takes a while to load. I want to add a loading bar to the button.

Code for button

this.onRelease = function() {  
filesize = obj.picture.getBytesTotal();  
loaded = obj.picture.getBytesLoaded();  
obj.preloader.\_visible = true;  
if (loaded != filesize) {  
obj.preloader.preload\_bar.\_xscale = 100\*loaded/filesize;  
} else {  
obj.preloader.\_visible = false;  
if (obj.picture.\_alpha\<100) {  
obj.picture.\_alpha += 10;  
}  
}  
};

It is not working. Can anyone help?

Thanks
