foldud skal ha 2 tryk??

Har følgende script som virker fint i det lange løb, men ved load af side skal linket have 2 tryk for at kickstarte!?

Er på herrens mark!!

<style>
.showit {
    display: block;
}
.hideit {
    display: none;
}
.lineit {
    display: inline;
}
</style>

<script type="text/javascript">
<!--

  var p, i, foundObj; 
  if(!theDoc) theDoc = document;

    theDoc = parent.frames[theObj.substring(p+1)].document;
    theObj = theObj.substring(0,p);}
