Month Display

Hi all,
I hav used <%= date_select(:timesheet,:created_at,
:order=>[:month,:year]) %>

If I use render_text <%=params[:timesheet][‘created_at(2i)’]%> in my
method,
I’m getting the month as 4 if select april. But I want to get directly
as April if i render it. So how to do this??

Thanks and Regards,
Harish
