Some help with the ushop button please

I have install my first hack,this ushop hack,but i have come to my first problem too. this is for the button on the navbar to get to the shop.

I am using aria skin, i put button no problem with this code: In HEADER Template:

PHP Code:

<!-- *** Start Shop *** --><if condition="$bbuserinfo['userid']"><td width="39"><table width="78" height="39" border="0" cellpadding="0" cellspacing="0">
      <tr>
        <td background="$stylevar[imgdir_misc]/shop.gif" id="shop"><A HREF="#shop"
        onMouseOver="JSFX.fadeIn('store')"
        onMouseOut="JSFX.fadeOut('store')"><img name="store" class="imgFader"
        src="$stylevar[imgdir_misc]/shop.gif"  width="78" height="39" border="0"></A><script type="text/javascript"> vbmenu_register("shop", 1); </script></td>
      </tr>
    </table></td></if>
<!-- *** End Shop *** --> 


and im putting the other part like this:HEADINCLUDE Template:

PHP Code:

JSFX.Rollover("store",    "$stylevar[imgdir_misc]/shop_over.gif"); 


Okay everything is good but when i push button on the frorum home nothing happen just the forum jump down little bit, but button is working good all other pages...is starnge..maybe i have made some templates error but i cant find were.
Like i say all other pages is working and hack is good to. This is the first time i try to hack so i was sure i get some trobules. funny i just get the button not working in only one place but in the postbit or other places it works okay? :ermm:
i have to sleep now to much headaces, please someone can tell me what mistake i am making.
Thanks for your time.
