I have 1 main mc that holds three seperate mcs. I’m trying to fire a function on the nav of one of the mcs from a “content” mc, passing in the button name/id from this content mc. I can trace to parent but the trace of the function within \_parent.\_parent is undefined.

Anyone have any suggestions, code chunk is below?

```auto

//code on button within a content mc trying to trigger the code in the nav mc.
this._parent._parent.productNavHolder.navRel(this._parent._parent.productNavHolder.btn3);

// trace comes back undefined
trace(this._parent._parent.productNavHolder.navRel);

```
