Problem loading variables when using multiple movie

I have a movie caled page1.swf (event calendar) which works fine as a stand alone movie. When I call this movie from my main.swf it doesn’t get the values from the database.
I know the problem is defining the correct levels but my knowledge about levels is = zero.
For a week I have been searching for an answer every where and I know the answer has been in front of me a lot of times but I don’t seam to get the point.

The page1.swf is loaded in to level 1 of the main.swf.
Here is the code I’m using in the page1.fla to get the values from the php file:

loadVariablesNum (“get_date.php”, _level0.currentlevel, “POST”);
_root.month = month;
_root.monthname = monthname;
_root.year = year;
gotoAndPlay(57);

This is the code used to define the drop downs if someone want to see events for specific dates:

monthcb.setValue(_root.monthname);
yearcb.setValue(_root.year);
function setmonth() {
monthcb.setEditable(false);
_root.month = monthcb.getValue();
monthcb.setEditable(true);
}
function setyear() {
yearcb.setEditable(false);
_root.year = yearcb.getValue();
yearcb.setEditable(true);
}
function get_calendar() {
_parent.play();
}
stop();

And this is how the value is returned after some one has picked a specifik date:

month = _root.month;
year = _root.year;
loadVariablesNum (“calendar_get.php”, _level0.currentlevel, “POST”);
stop();

I would appriciate it if some one could take a look at codes and tell me what levels should I define in order for my calendar to work within the main.swf

Thank you in advance.
