How to make the Date Prompts blank in Cognos10.2

[s.aravindkumar]

Hi All,

I am using cognos 10.2.1 and got stuck with the below issue

I have a date prompt which is a mandatory field, I used below javascript to make this prompt blank

<script language="javascript">
document.formWarpRequest.elements["txtDatetodate"].value='';
</script>

But, when I run the query I am getting date prompt page twice.

So,Can anyone please say why is this happening? and how to make the date prompt blank in cognos 10.2

Thanks and Regards,
