Scrolling marquee, alternating marquee won't work in all browsers Options

[Rigit]

I've got a scrolling marquee on my website that also contains a link. The marquee itself is recognized by all browsers and so is the link. But Apple Safari and Google Chrome will not alternate. The text goes all the way to the left and just stays there. Here is the code:

/span>
<marquee behavior="alternate" direction="left"
bgcolor="#99FFFF" scrollamount="4"
onmouseover="this.stop()" onmouseout="this.start()()"><font
color="#ff9900" size="+2"><a
href="http://www.crlwc.com/picnic.html">Celebrate
Recovery is having a picnic! Click here for details</a></font></marquee>

I tried to remove the direction left part but it had no effect on getting the text to move. I'm new at HTML and most of this kind of techy stuff I get by Google. I've learned what it means more or less and I can manipulate things to get them to do what I want. Just not with this. I've tried everything. Juggling with the wording, adding commands and stuff but to no avail. Suggestions?
