Try this (not tested it myself), it should at least fix your javascript.
But I think you should read this http://www.w3schools.com/tags/tag_area.aspCode:<script type="text/javascript"> function area1Clicked () { var div1 = document.getElementById("div1"); div1.style.display = "block"; } </script> <area name="area1" onClick="area1Clicked()"> <div id="div1" style="display:none;"> <h2>HI</h2> </div>
The area tag must always be nested within a map tag and you must also provide an alt attribute. Also, I'm not sure what happens if you don't specify the coords attribute.
