Hello;

I’d like to make a 30x30 grid system.  
When Flash is launched it selects a random box in the 30x30 grid and then  
displays the boxes there( alpha 0 to alpha 100) then the other 4 boxes above,bottom , left and to the right of it and then continue like this until this ends (whole grid displayed) Please , I need help.

I wrote smth like that:

function displayBox() {  
startPoint = random(amH\*amV);  
box.duplicateMovieClip(“box”+startPoint, depth);  
focus = this[“box”+int(startPoint)];  
focusU = this[“box”+int(startPoint-amH)];  
focusD = this[“box”+int(startPoint+amH)];  
focusL = this[“box”+int(startPoint-1)];  
focusR = this[“box”+int(startPoint+1)];  
visibleBoxes.push(focus,focusU,focusD,focusL,focusR);

```
trace(focus+" "+focusU+" "+focusD+" "+focusL+" "+focusR);
trace(visibleBoxes);
}

```

displayBox();

but cant calculate further.
