Your embedding code for two TiltViewer galleries on the same page should look something like this:
<div id="flashcontent1">TiltViewer requires JavaScript and the latest Flash player. <a href="http://www.macromedia.com/go/getflashplayer/">Get Flash here.</a></div>
<script type="text/javascript">
var fo1 = new SWFObject("TiltViewer.swf", "viewer1", "100%", "100%", "9.0.28", "#000000");
fo1.addVariable("useFlickr", "false");
fo1.addVariable("xmlURL", "gallery1.xml");
fo1.addVariable("maxJPGSize","640");
fo1.addVariable("useReloadButton", "false");
fo1.addVariable("columns", "3");
fo1.addVariable("rows", "3");
fo1.addParam("allowFullScreen","true");
fo1.write("flashcontent1");
</script>
<div id="flashcontent2">TiltViewer requires JavaScript and the latest Flash player. <a href="http://www.macromedia.com/go/getflashplayer/">Get Flash here.</a></div>
<script type="text/javascript">
var fo2 = new SWFObject("TiltViewer.swf", "viewer2", "100%", "100%", "9.0.28", "#000000");
fo2.addVariable("useFlickr", "false");
fo2.addVariable("xmlURL", "gallery2.xml");
fo2.addVariable("maxJPGSize","640");
fo2.addVariable("useReloadButton", "false");
fo2.addVariable("columns", "3");
fo2.addVariable("rows", "3");
fo2.addParam("allowFullScreen","true");
fo2.write("flashcontent2");
</script>
If you continue to experience difficulties, please post the URL to your web page so that we can take a look.
