[S!p]

When i load this script from url work fine. Only after include get error.
It`s from code (js) but i don`t know what it means:

PHP Code:

            function dead(wat) 
            { 
                alert("Server side error. Dying:" + wat); 
            } 
            function cback(data, textStatus) 
            { 
                if (textStatus == "success") 
                { 
                    var lines = data.split("\n"); 
                    mark = lines[0]; 
                    if (mark + 0 == 0) die(3); 
                    var line; 
                    var scrollme = new Array(); 
                    for(var i = 1; i < lines.length; i++) 
                    { 
                        line = lines[i].split("\x01"); 
                        // 0 srvid 
                        // 1 string 
                        // Formatted serverside 
                        if ($("#dscrollto_" + line[0]).offset().top <= $("#dbody_" + line[0]).height() + $("#dbody_" + line[0]).offset().top)
                            if (!scrollme[line[0]]) scrollme[line[0]] = true; 
                        if (line.length != 2) return dead("1"); 
                        var box = $("#dat_" + line[0]); 
                        if (!box) return dead("2"); 
                        if (loading) 
                        { 
                            box.html(line[1]); 
                            loading = 0; 
                        } 
                        else 
                        { 
                            box.append(line[1]); 
                        } 
                        box.children(".line:last").fadeIn(500); 
                    }
