Looping timer?

I’m trying to get some text to simply fade out and back an infinite number of times. Like a slow blink. Using a timer class and a couple functions, i can get it to work once, but it won’t keep repeating. What’s wrong with my code?

ActionScript Code:
[LEFT][COLOR=#0000FF]import[/COLOR] caurina.[COLOR=#000080]transitions[/COLOR].*;

[COLOR=#808080]// alpha 0% timer[/COLOR]
[COLOR=#000000]var[/COLOR] hdrTimer:Timer = [COLOR=#000000]new[/COLOR] Timer[COLOR=#000000]([/COLOR][COLOR=#000080]1000[/COLOR], [COLOR=#000080]0[/COLOR][COLOR=#000000])[/COLOR];
hdrTimer.[COLOR=#000080]addEventListener[/COLOR][COLOR=#000000]([/COLOR]TimerEvent.[COLOR=#000080]TIMER[/COLOR], timerListener[COLOR=#000000])[/COLOR];

[COLOR=#808080]// alpha 100% timer[/COLOR]
[COLOR=#000000]var[/COLOR] hdrTimer2:Timer = [COLOR=#000000]new[/COLOR] Timer[COLOR=#000000]([/COLOR][COLOR=#000080]1000[/COLOR], [COLOR=#000080]0[/COLOR][COLOR=#000000])[/COLOR];
hdrTimer2.[COLOR=#000080]addEventListener[/COLOR][COLOR=#000000]([/COLOR]TimerEvent.[COLOR=#000080]TIMER[/COLOR], timerListener2[COLOR=#000000])[/COLOR];
