I am using Flash 8. Progressive video, video template from adobe with screens, FLV Playback component. I want to grey out (\_alpha) my nav buttons until bytes are loaded to that point so that visitors are not clicking on buttons that won’t work yet. I have the following script on a separate layer, frame 1. The alpha won’t change. What am I missing? thank you in advance:

//\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*_greying out buttons  
slide6\_btn.\_alpha = 10;  
slide11\_btn.\_alpha = 10;  
slide17\_btn.\_alpha = 10;  
slide21\_btn.\_alpha = 10;  
slide23\_btn.\_alpha = 10;  
import mx.video._;  
var listenerObject:Object = new Object();  
listenerObject.ready = function(eventObject:Object):Void {

if (display.bytesLoaded \> 2140076) {  
slide6\_btn.\_alpha = 100;  
}  
if (display.bytesLoaded \> 3923473) {  
slide11\_btn.\_alpha = 100;  
}  
if (display.bytesLoaded\>6063549) {  
slide17\_btn.\_alpha = 100;  
}  
if (display.bytesLoaded\>7490267) {  
slide21\_btn.\_alpha = 100;  
}  
if (display.bytesLoaded\>8203626) {  
slide23\_btn.\_alpha = 100;  
}  
}
