I'm having a slight problem with the code I'm using for an RSS subscription box. It doesn't seem to work in IE and in firefox the button moves when clicked. Any tips? Am I doing something wrong? <div> <div style="float:left;"> <form style="background: none; border:0px solid #ccc;padding:3px;text-align:center;" action="http://www.feedburner.com/fb/a/emailverify" method="post" target="popupwindow" onsubmit="window.open('http://www.feedburner.com/fb/a/emailverifySubmit?feedId=2125782', 'popupwindow', 'scrollbars=yes,width=550,height=520');return true"> <input type="text" value="Enter e-mail address..." id="emailtext" name="email" onblur="if (this.value == '') {this.value = 'Enter e-mail address...';}" onfocus="if (this.value == 'Enter e-mail address...') {this.value = '';}" style="margin-bottom:4px;" maxlength="40" /> <input type="hidden" value="http://feeds.feedburner.com/~e?ffid=2125782" name="url"/><input type="hidden" value="ForWhichItStood: A Blog on Liberty" name="title"/> <input type="hidden" name="loc" value="en_US"/><br><input type="image" src="http://www.forwhichitstood.org/wp-content/themes/options/images/subscribenew.gif" value="Subscribe" /></form> </div> <div style="float:right;"><a href="http://feeds.feedburner.com/forwhichitstood"><img src="http://www.forwhichitstood.org/wp-content/themes/options/images/rssicon.png"></a> </div> </div> Code (markup): Thanks!
