Hiding /disabling a single tab from tabbed options.

Hi
Thank you for getting back to me.
Yes I used just a choice control to show as tabbed options on the form.
Just to give you an overview:
so here I have different panels to show or hide when user go for new request, extension, amend or cancellation.
Here we have the requirement such that the user can allow to apply for extension or amendment or cancellation only after new request approved.
and I would like to hide all the three tabs Extension, Amendment, Cancellation when the stage is at "New request"
Below is the code I tried.
NWF$(document).ready(function()
{ var Query = NWF$('#' + jsstagectrl).val();
if(Query=="New Request")
{
NWF$('#'+jsTabbuttons).find('input[value='New request']').attr('checked', 'checked');

NWF$('#'+jsTabbuttons).find('input[value='Extension']').hide();
NWF$('#'+jsTabbuttons).find('input[value='Amendment']').hide();
NWF$('#'+jsTabbuttons).find('input[value='Cancellation']').hide();
}
});
But its not working as required and I am not sure where I am going wrong.
Can you please show me the way?
