Javascript not displaying popup

I want to make a pop up window appear on the center of the screen,however when i use marginTop property the window does not appear.If remove marginTop property it appears always on upper left side corner. I use php 5.4 . What am I doing wrong?

function show_popup(id) {
        if (document.getElementById){
            obj = document.getElementById(id);

            if (obj.style.display == "none") {
               obj.style.marginTop = 20%;  //if i remove this line it works 
               obj.style.display = "";

            }
        }

    }

I think you need to apply "20%" for that like as below 

obj.style.marginTop = "20%";

Check Syntax over here Style marginTop Property

Did you try to set obj.style.marginTop = "20%" (with the ") ?
