http://www.dynamicdrive.com/dynamici...autocenter.htm

<a href="http://mysite.com/lyrics/lyrics.php?song='.$row['other'].'" onclick="NewWindow(this.href,\'Lyrics\',\'625\',\'500\',\'yes\');return false">View</a>

if you are wondering what I have all of thoes slashes, I am using it with php:

echo '<td bgcolor="#ffffff"><a href="http://mysite.com/lyrics/lyrics.php?song='.$row['other'].'" onclick="NewWindow(this.href,\'Lyrics\',\'625\',\'500\',\'yes\');return false">View</a>'; 

The script is working fine in Mozilla 1.7.12, IE 6.0, Opera8.51, but it is not working in FireFox. What am I doing wrong? And yes, I would include a link to the problematic page, but my site has not gone live I am still working on my local computer. Thanks for any help.
