When 2 chars on a page only one is showing.

As the title says, sometimes, if I have 2 charts on a page they get the same ID and the second one just overwrites the first one:

<div id="47b9faa99f89b"></div> 
                 <script type="text/javascript" src="/sites/all/modules/open_flash_chart_api/js/swfobject.js"></script> 
                 <script type="text/javascript"> 
                    var so = new SWFObject("/sites/all/modules/open_flash_chart_api/open-flash-chart.swf", "ofc", "200", "200", "9", "#FFFFFF"); 
                    so.addVariable("variables","true");so.addVariable("title","Bar Chart, {font-size: 20px;}");so.addVariable("x_label_style","10,#9933CC,0,2");so.addVariable("x_axis_steps","2");so.addVariable("y_legend","Open Flash Chart,12,#736AFF");so.addVariable("y2_legend","");so.addVariable("y_ticks","5,10,4");so.addVariable("bar","50,#9933CC,#8010A0,Page views");so.addVariable("values","7,7,7,5,9,5");so.addVariable("x_labels","January,February,March,April,May,June");so.addVariable("y_min","0");so.addVariable("y_max","10");so.addVariable("y2_min","");so.addVariable("y2_max","");so.addVariable("bg_colour","0xDFFFDF");so.write("47b9faa99f89b");

                 </script>

I know you work on v.3 and I'm in no hurry so I just want to make sure you take this into acount for v.3

Thank you for a great module!
