Rails - Oct 2005 - make select list with days and select a day

hey, i want a list of daysnumber 1 through 31, and a value must be selected, the
one from the database

the purpose is that a date is retrieved from the database, broken up in 3
selects (year, month , day), and select the value from the database

in my controller i create the day list


@day = @start_time_local.strftime(''%d'') # this date is from
the database,
filtered out the day
@days = []
	1.upto(31) do |d|
	@days.push( { d => d})
end

in my rhtml i want the list of days, and the selected value must be @day

<select name="time_entry[start_day]">
<% options_for_select( @days, @day ) %>
</select>

thanks in advance
