test if a child exsists

Hi All,

I need to test to see if a child exists in a object... If it does I need to remove it, currently I am just trying to remove it and I am obviously getting a stack of runtime errors complaining that the child doesn't exist

Thanks

Xavier

thats not what i need.

This is my code:

if (exclusionName != "DP_TL"){
                  removeChild(DP_TL);
            }else{
                  activeDP = DP_TL;
            }

needs to be something like:

if (exclusionName != "DP_TL" && childExists(DP_TL)){
                  removeChild(DP_TL);
            }else{
                  activeDP = DP_TL;
            }

I know that "childExists()" isnt a real function but thats to give you an idea as to what i mean.

Hello,

Thanks for giving me an assist!

Just to be sure you're clear and to help you optimize. If the following line from your accepted solution returns a reference to an object:

var box2_mc = container_mc.getChildByName("Box2_mc");

Then it's not necessary to use the 'contains()' method since the variable would be undefined if no child exists by that name.

Good luck and thanks again.
