well i wont go into action scripting but basically you should do something like that:

- a loops that checks if the spacebar is press
- a function which will increment the size of a movie clip if the above loop is true
- another function in the loop which will decrement the size of the MC until it has reached zero…

Sorry i really dont have free time to make a fla about it…

I am not sure I fully understand what you are trying to do, but create a bar movie clip with the registration point on the left middle.

Then apply these actions to a frame…  
[AS]bar.\_width = 1;  
\_root.onEnterFrame = function() {  
if (Key.isDown(Key.SPACE)) {  
bar.\_width += 1;  
if (bar.\_width\>=100) {  
bar.\_width = 100;  
}  
} else {  
bar.\_width -= 1;  
if (bar.\_width\<=1) {  
bar.\_width = 1;  
}  
}  
};[/AS]

Close?
