  <p>I have one dynamic Google lineChart with JSON and 3 static Google gaugeCharts... I want to put them all on one html page. I did look for the answer before asking this question; for instance I don't think I have any variables with the same name. All these charts work. The lineChart works (in a separate html file) completely and the 3 gaugeCharts work as well (also separately in one html document). Honestly I'm pretty lost and can't seem to get my working charts to be shown together in harmony. Can you please help to solve this? As you can see I added all the css html javascript jquery and JSON code. But the problem is just in the html file somewhere. </p>
