submit\_btn.onRelease = function() {  
area = (height\*width);  
};

Here is the code I was trying to use. I am trying to learn flash and wanted to make a simple file where you put a number in the input text boxes( linked to height and width) and the answer would come in a dynamic text box(linked to area) When I test the movie I get Nan in the in the dynamic text box. Could use some help to understand what is going on. I attached the file I made.
