Fluid Layout - stop changing resize position when movieclip is at certain position

Question

Hello. I have been trying things out for hours, and I still can't get it.
I am following this Fluid Layout tutorial: http://active.tutsplus.com/tutorials/web-design/build-a-fluid-website-layout/
I added a Menu_mc on my stage. Initially, this should be at the center of the stage and when I click on it, it will tween on the upper left corner of the browser. However, when I resize the browser, the Menu_mc goes back to the center of the screen.
I have tried separating a different actionscript file where it is specifically for initialization of the object and another one for resizing. And then when I call it on my main AS file it goes like this:
// Add the symbols to stage
             var Menu_mc = new Menu_MC();
             addChild(Menu_mc);
             // Apply the alignment to the middle
             var Menu_InitParam = {
                 x:0.53,
                 y:0.35,
                 offsetX: -Menu_mc.width/2,
                 offsetY: -Menu_mc.height/2
             new InitFluidObject(Menu_mc,Menu_InitParam);
             var Menu_ResizeParam = {
                 x:Menu_mc.x,
                 y:Menu_mc.y,
                 offsetX: -Menu_mc.width/2,
                 offsetY: -Menu_mc.height/2
             new FluidObject(Menu_mc,Menu_ResizeParam);
But it seems futile. Could anyone please help? Thanks a lot!

Do you have any useful resources that I could perhaps check out? Haven't explored ANY javascript before =)
