how to add gadget "latest articles" blogger

1. Insert latest articles on blogger
If in our blog feel the need to see the latest articles posted, we can use gadget that
allows you to insert the link of your post automatically every time you post. There
will be a flow of securities with a number reset and changed course. To insert the
gadget bloggers go on Desing> Layout> Add Gadget> Gadgets and we paste
the following HTML code:
<span style="line-height:100%;Verdana&quot;,&quot;sans-serif&quot;font-
family:&quot;;font-size:12.0pt;"><script style="text/javascript">
function ultimipost(json) {
document.write('<ul>');for (var i = 0; i < numposts; i++) {
document.write('<li>');
var entry = json.feed.entry[i];
var posttitle = entry.title.$t;
var posturl;
if (i == json.feed.entry.length) break;
for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
posturl = entry.link[k].href;
break;
}
}
posttitle = posttitle.link(posturl);
var readmorelink = "(leggi tutto)";
readmorelink = readmorelink.link(posturl);
var postdate = entry.published.$t;
var cdyear = postdate.substring(0,4);

2. var cdmonth = postdate.substring(5,7);
var cdday = postdate.substring(8,10);
var monthnames = new Array();
monthnames[1] = "Gen";
monthnames[2] = "Feb";
monthnames[3] = "Mar";
monthnames[4] = "Apr";
monthnames[5] = "Mag";
monthnames[6] = "Giu";
monthnames[7] = "Lug";
monthnames[8] = "Ago";
monthnames[9] = "Set";
monthnames[10] = "Ott";
monthnames[11] = "Nov";
monthnames[12] = "Dic";
if ("content" in entry) {
var postcontent = entry.content.$t;
} else if ("summary" in entry) {
var postcontent = entry.summary.$t;
} else
var postcontent = "";
var re = /<S[^>]*>/g;
postcontent = postcontent.replace(re, "");
document.write(posttitle);
if (showpostdate == true) document.write(' - ' + cdday + ' ' +
monthnames[parseInt(cdmonth,10)]+ ' ');
if (showpostsummary == true) {

3. if (postcontent.length < numchars) {
document.write(postcontent);
} else {
postcontent = postcontent.substring(0, numchars);
var quoteEnd = postcontent.lastIndexOf(" ");
postcontent = postcontent.substring(0,quoteEnd);
document.write(postcontent + '...' + readmorelink);
}
}
document.write('</li>');
}
document.write('</ul>');
document.write('<div id="crdt" style="font-size:70%;text-align:center"><p><a
href="http://goo.gl/SEGfw">Get Widget</a></div>');
}
</script>
<script style="text/javascript">
var numposts = 18;
var showpostdate = false;
var showpostsummary = false;
var numchars = 100;
