    body onload problem

    I am working with JSP and have a top and bottom jsp for each screen of
    my application. I call javascript event that processess a form on one
    of these screens.

    This works fine on screen 1 but on screen two where the form is not
    present the function is still called and i get and error message in the
    browser saying that

    'document.searc hForm.moveFromD ate' is not an object.

    Is it possible to check that the form is present before the function
    trys to do anything?

    Any help would be much appreciated.

    Thanks
    Clive

      Check
      <body onload="if (document.forms .searchForm &&
      document.forms. searchForm.elem ents.moveFromDa te) {
      // access
      document.forms. searchForm.elem ents.moveFromDa te here
      }">
