Making my own Feedblitz widget

So, I’m using Feedblitz for my RSS and I love the way I have it set up, except I want the “Go” button on the same line as the input field. Can you help me? (This is in the HTML module on the widgets page.)

My URL: https://www.oicmoments.com (upper right hand corner)

The code I’m using

<div class="fb-container"><div class="fbf-text"> </div><form class="fbf-widget" style="display: inline;" action="https://www.feedblitz.com/f/f.fbz?AddNewUserDirect" method="POST" name="FeedBlitz_c3cda9e8ea5511e2b30f002590771423"><input align="middle" type="text" maxlength="64" name="EMAIL" size="26" value="Subscribe by email" class="subscription_email" /><input type="hidden" maxlength="64" name="EMAIL_" size="25" value="" /> <input type="hidden" maxlength="64" name="EMAIL_ADDRESS" size="25" value="" /> <input type="hidden" name="type" value="1" /> <input type="hidden" name="sort" value="1" /><input type="hidden" name="SiteScope" value="876878" /> <input type="hidden" name="PUBLISHER" value="31964548" /> <input style="display:inline" class="subscription_btn" onclick="FeedBlitz_c3cda9e8ea5511e2b30f002590771423s(this.form);" type="button" value="Go " /></form></div>

<script type="text/javascript" language="Javascript">// <![CDATA[
