function startPreview() {
    var z,x=0,y=0;

    if ( document.getElementById("selectTemplate").selectedIndex != 1 ) { // if not IE 7 template
        var s = document.getElementById("selectZoom");
        z = s.options[s.selectedIndex].value;
    }
    else {
        var s = document.getElementById("selectZoom");
        var s1 = document.getElementById("selectPages");

        var o = parseInt(s1.options[s1.selectedIndex].value);

        switch (o) {
            case 0: // zoomed one page
                z = s.options[s.selectedIndex].value;
                break;

            case 2: // the rest are multi-page views.
                z = 0;
