I Don't know if this has to deal with suffusion messing stuff up or not BUT. I did exactly as my friend did and his website doesn't have the same problem...
OK so I'm using 'feedburner' I'm copying and pasting a code into the regular 'text widget'. This is the code actually:
<form style="border:1px solid #ccc;padding:3px;text-align:center;" action="http://feedburner.google.com/fb/a/mailverify" method="post" target="popupwindow" onsubmit="window.open('http://feedburner.google.com/fb/a/mailverify?uri=AndrewWkMusic', 'popupwindow', 'scrollbars=yes,width=550,height=520');return true"><p>Enter your email address:</p><p><input type="text" style="width:140px" name="email"/></p><input type="hidden" value="AndrewWkMusic" name="uri"/><input type="hidden" name="loc" value="en_US"/><input type="submit" value="Subscribe" /><p>Delivered by <a href="http://feedburner.google.com" target="_blank">FeedBurner</a></p></form>
When I do so it acts all fidgety and goes to my old RSS feed and doesn't even allow the user to submit an email address. You can see the difference between the two sites here:
How do I fix this so it works like its supposed to.
