Hi fellows I am still waiting  
Here what i am doing I load a swf using loadMovieNum now I want to do

1. Somehow pass the values to the called swf from the caller swf
2. Another thing I want is that I want to get the currentframes of caller swf  
that means I need to have two way communication between caller and called swf. i.e. caller should know what the called status is and vice versa

Just put a var in \_root, and when the called movie is loaded inside the caller, they share \_root. So they can both read and write vars in \_root, which you can use to let them ‘communicate’.

Since you’re using loadMovieNum I assume you’re loading movies into different levels then want to communicate between levels. If this is the case you can use the \_levelX. It’s used in the same way \_root is but \_root, refers to the root timeline of the current level. \_levelX refers to the main timeline of the X level.

So if there’s a variable called timer on the main timeline of the movie in level 3, and you want to acces it from a movie in level 10 use \_level3.timer
