I need to drag out some variable from my HTML , eg:  
loaderInfo.parameters.limitext;

But I want to reserve a default value for that in case the HTML is broken , so I write:  
if (loaderInfo.parameters.limitext == null)  
{  
var extension\_str:String = “_.jpg;_.gif;\*.png”;  
}  
else  
{  
var extension\_str:String = loaderInfo.parameters.limitext;  
}  
Thus way I get a warning. So … any good idea to avoid this ?
