            </table></td>

    </tfoot>

containing a button

<input type="submit"    
name="dnn$ctr521$View$episkopisiGrid$ctl00$ctl03$ctl01$ctl10"   
value=" " title="Next Page" class="rgPageNext" />                           

for some reason i just cant get it to click on it. I tried this

subworks.query("tfoot").queryAll("div").get(3).query("input").click();

Which is the correct element, since i am getting the correct value (next page) when i call .getValue()

It seems that the page doesnt change after i run this command. I use .getBody() but i am getting the same html as before the click command.

Any help?
