Multiple Fusion Charts in WordPress Post

I’m using FusionChartsFree and have successfully managed to get the charts working, but I’m not a programmer, so I just follow instructions, lol.

This is the code I’m using, but as you probably already know, I have to change some values to put another chart, and I don’t know what to change. This is my site.

<script src="https://mydomain.com/FusionChartsFree/JSClass/FusionCharts.js" type="text/javascript"></script> <script type="text/javascript">// <![CDATA[
var myChartId = 'chart1';
var myChartSWF = 'https://mydomain.com/FusionChartsFree/Charts/FCF_Column3D.swf';
var myChartWidth = '600';
var myChartHeight = '400';
var myDataXML = 'https://mydomain.com/FusionChartsData/Lobbying.xml';
document.write('<span id="' + myChartId + 'container">')
var chartObj = new FusionCharts(myChartSWF, myChartId, myChartWidth, myChartHeight);
chartObj.setDataURL(myDataXML);
chartObj.render(myChartId + 'container'); // ]]></script>

I changed the .xml file and the .swf file, but nothing happens. Any ideas?

The guy that give the advice on his blog said

Tips: To add more than one chart per post, simply copy the second <script> block and place it anywhere else in your page and provide new values for all the variables starting with “my”.
