Window Recognition problem

coded in c#.

I tried to pass object mpanel to the function findTxnLink but object is not recognised. error say object doesn't recognised.  wheather I am implemented correctly. I am in process of creating in gendralised function. I have to put findTxnlink function is seperate unit. I tried with useunit also same result is persist. guide me how to resolve this problem.

function findTxnLink(mpanel, objectid)

{

    Log["Message"]("pass into condition stmt1");        

    var Props, Values, w;

   

    // Creates arrays of property names and values

    Props = new Array("ObjectType", "ObjectIdentifier");

    Values = new Array("Link", "objectid");

      Log["Message"]("pass into condition stmt2");    

    // Searches for the linknode select that item

    w = mpanel["FindChild"](Props,Values, 3);

    w["Click"]();   

     Log["Message"]("pass into condition stmt3");    

   

}

function test()

{

  var iexplore;

  var frame;

  var form;

  var panel;

  var textbox;

  var table;

  var mpanel;

 

  iexplore = Aliases["iexplore"];

  frame = iexplore["pageMiserBa"]["applicframe"]["mainframe1"];

  form = frame["Mainmenuform"];

  panel = form["Txntreepanel"];

  mpanel = panel["panelMenutxndiv"]["menupanel"];

     c=findTxnLink(mpanel, "Node0");

     c["Click"]();   

}
