Help with mechanize and javascript

Hello all, this is my first post to this list.  I am fairly new to
WWW::Mechanize, but I have been in pretty good shape so far.  I have run
into a page that has a javascript link to another page and I can't get by
it. I am trying to use push_input to get by that way, but I can't seem to
translate the javascript to see what I should configure. Below is the
javascript snippet. Any help is appreciated.

Thanks.

<script language="JavaScript" type="text/javascript">
     function setAndSubmit(actionName, formObj, varNameAndValueArray)
     {
          for(var i = 0; i < varNameAndValueArray.length; ++i)
          {
               eval("document."+formObj.name+"."+varNameAndValueArray[i]+".value=\""+varNameAndValueArray[++i]+"\";");
          }

         //if NN4
         if(document.layers)
         {
             var whichDummy;
             //if there is more than one form variable named dummy
             //find the first one that hasn't been renamed and use it
             if( formObj.dummy.length != null )
             {
                 var done = false;
                 for(i=0; i < formObj.dummy.length && !done; ++i)
                 {
                     if( formObj.dummy[i].name == "dummy" )
                     {
                         whichDummy = i;
                         done = true;
                     }
                 }
                 if( !done )
                 {
                     alert("Error: All dummy variables used up!");
                 }

eval("document."+formObj.name+".dummy[whichDummy].name=\""+actionName+".x\"");
             }
             //if there is only one dummy field, just use it
             else
             {

eval("document."+formObj.name+".dummy.name=\""+actionName+".x\"");
             }
             formObj.submit();
         }
     }
</script>


Above is the function that gets passed the variables, here is the
snippet that calls the function.


<input type=hidden name=GroupId value="">
<td valign=top>
<!-- ugly script to write out image link for netscape or image button for IE-->
<script language="JavaScript" type="text/javascript">
    //if NN4
    if(document.layers)
    {
        document.write("<input type=\"hidden\" name=\"dummy\" value=\"1\" />");
        document.write("<a
href=\"javascript:setAndSubmit('EDIT_STORE_RULES_GROUP',
document.updateAccount, ['GroupId', '524789']);\"><img
src=\"/nhin/jsp/images/editstorehours.gif\"
alt=\"EDIT_STORE_RULES_GROUP\" border=\"0\" /></a>");
    }
    else
    {
        document.write("<input type=image
src=\"/nhin/jsp/images/editstorehours.gif\"
name=\"EDIT_STORE_RULES_GROUP\"
onclick=\"javascript:setAndSubmit('EDIT_STORE_RULES_GROUP',
document.updateAccount, ['GroupId', '524789']);\"
alt=\"EDIT_STORE_RULES_GROUP\" />");
    }
</script>
