Good evening,

I changed for this method :

<div id="timeline-embed"></div>
<script type="text/javascript">
   var timeline_config = {
	width: "905",
	height: "650",
	lang: 'fr',
	source: 'https://docs.google.com/spreadsheet/pub?key=0ArmUqccrDtsKdDd6R2lCeU04Wm1pN3dvV3BBeGI4S2c&output=html'
	    }
	</script>
	<script type="text/javascript" src="<?php bloginfo( 'template_directory' ); ?>/compiled/js/timeline-embed.js"></script>

the timeline works well in IE and Chrome but does not work in Opera and Firefox. You can view the page on my site: http://amicaledetection.com/association/

Thank you for any help.
