I have an object that I push onto the stage every 5 seconds called Rock, when the rock is added, I pull its speed from a function called globalSpeed, it then returns a random number, however, the first time this function is called, it gets an undefined number and causes my rock to freeze, but everything else after that works, trace looks like:

undefined  
40  
35  
67  
etc

what could be causing this

```
ActionScript Code:
[LEFT][COLOR=#000000] **var** [/COLOR] myRock:Rock = [COLOR=#000000] **new** [/COLOR] Rock[COLOR=#000000]([/COLOR]globalSpeed[COLOR=#000000]([/COLOR]myRock[COLOR=#000000])[/COLOR][COLOR=#000000])[/COLOR];

```

[COLOR=#000000] **function** [/COLOR] globalSpeedCOLOR=#000000[/COLOR][COLOR=#000000]{[/COLOR]  
[COLOR=#0000FF]if[/COLOR][COLOR=#000000]([/COLOR]thisObj is Rock[COLOR=#000000])[/COLOR][COLOR=#000000]{[/COLOR]  
[COLOR=#0000FF]return[/COLOR] [COLOR=#0000FF]Math[/COLOR].[COLOR=#0000FF]random[/COLOR]COLOR=#000000[/COLOR]\*[COLOR=#000080]40[/COLOR]+[COLOR=#000080]50[/COLOR];

```auto
var myRock:Rock = new Rock(globalSpeed(myRock));

```

firstly u are creating variable myRock then u are passing empty var to globalSpeed function, then u create new rock.  
U have created an “impass”
