Classic ASP Discussion - Selecting current hour in dropdown list

<select name="u_day" class="form_field">
<% for counter = 1 to 31 %>
<option <%
if counter = day(rsPosts.Fields.Item("PostDate").value) then %>
selected
<% end if %>
value="<%= counter %>">
<%= counter %></option>
<% next %>
</select>

<select size="1" name="u_month" class="form_field">
<% for counter = 1 to 12 %>
<option <%
if counter = month(rsPosts.Fields.Item("PostDate").value) then %> selected <% end if %> value="<%= counter %>"><%= MonthName(counter) %></option>
<% next %>
</select>

<select size="1" name="u_year" class="form_field">
<% for counter = 2005 to 2010 %>
<option <%
if counter =year(rsPosts.Fields.Item("PostDate").value) then %> selected <%
end if %> value="<%= counter %>"><%= counter %></option>
<% next %>
</select>

Now for the hour I'm using this

<select name="u_time" class="form_field">
<% for counter = 8 to 22 %>
<option <%
if counter = hour(rsPosts.Fields.Item("PostDate").value) then %> selected <% end if %> value="<%= counter %>:00:00"><%= counter %>:00:00</option>
<% next %>
</select>

I'malso using a javascript functio to get the dates from the fields

<form ACTION="<%=MM_editAction%>" METHOD="POST" name="form1" onSubmit="GetDate()">

the javascript GetDate():

<script language="JavaScript">

</script>

maybe I'm doing something wrong here

and the variables
<%
u_date=request.form("u_date")
u_month=request.form("u_month")
u_day=request.form("u_day")
u_year=request.form("u_year")
u_time=request.form("u_time")
%>

If I choose 'edit post' the hour comes correct in the dropdown list, but when I choose update, even when I leave the current hour selected, it removes the hour in the DB date field, only the date get's updated and the time is deleted.
