Search box on shopping cart page does not work

When you are viewing your shopping cart, the search box in the upper right does not function properly and the search results page is in a different format. The HTML for it is different than the search box on the main store page:

Main Store Page Search box HTML:

input name="dnn$txtSearch" type="text" id="dnn_txtSearch" />
  </td>
  <td width="45" height="38">
  input type="image" name="dnn$btnSearch" id="dnn_btnSearch" src="[URL="http://forums.parallax.com/view-source:https://www.parallax.com/Portals/0/Skins/skins/images/SearchBox-Background_05.jpg"]../../../Portals/0/Skins/skins/images/SearchBox-Background_05.jpg[/URL]" style="border-width:0px;"             

Shopping Cart Search box HTML:

input name="dnn$txtSearch" type="text" id="dnn_txtSearch" /> 
  </td>
  <td width="45" height="38">
  input type="image" name="dnn$btnSearch" id="dnn_btnSearch" src="[URL="http://forums.parallax.com/view-source:https://www.parallax.com/Portals/_default/Skins/ArrowDesigns-Parallax/images/SearchBox-Background_05.jpg"]../../../../Portals/_default/Skins/ArrowDesigns-Parallax/images/SearchBox-Background_05.jpg[/URL]" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;dnn$btnSearch&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" style="border-width:0px;" 

Note: I removed the < that was in front of the Input tags because the forum software alters the text if they are there.
