Hi frds,

I got big trouble in creating svg polygon dynamically.
Here is my javascript code

<script type="text/javascript">

        var svgNS = "http://www.w3.org/2000/svg";
                function CreateHexagon(xx,yy) {
        var x1 = parseInt(xx), y1 = parseInt(yy)
            var myHexagon = document.createElementNS(svgNS, "polygon");
            myHexagon.setAttributeNS(null, "id", "Hexagon");
            myHexagon.setAttributeNS(null, "points", ""((x1 / 4), 0)((3 * x1) / 4, 0)((x1), (y1 / 2))((3 * x1) / 4, y1)((x1 / 4), y)(0, (y1 / 2))); ""
           // myHexagon.setAttributeNS(null, "points", "50,5   100,5  125,30  125,80 100,105 50,105  25,80  25, 30");
            myHexagon.setAttributeNS(null, "fill", "blue");
            myHexagon.setAttributeNS(null, "stroke", "none");
            document.getElementById('mySVG').appendChild(myHexagon);
        }

    </script>

and this is my code behind

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "tn1", "<script>CreateHexagon(978,183)</script>", false);

please please solve my trouble.This is an error
