Cognos 11.0.7 CustomControl JavaScript to remove top 2 lines from value prompt

[joseph123]

Hi

Does any one has JavScript code to remove top 2 lines from value prompt.
Does any one knows method and syntax to remove a line.

<script language="javascript">
var f = getFormWarpRequest();
var list = f._oLstChoicesplaceyourpromptnamehere;

list.remove(0);
document.formWarpRequest._oLstChoicesplaceyourpromptnamehere[0].text =  '  ';
list.removeAttribute("hasLabel");
</script>

===============================

Notes:  replace placeyourpromptnamehere with your prompt name
in the two places.
