Sorry I did not provide more details. Another email has been sent with code
snippet from view (and included below). Please pardon my incompleteness as I
am very new to this type of development.
Is it okay to use a hidden field? I have seen talk of hidden fields in my
Google searches but do not understand how to use it, but then, I have been
focused on just assigning to the parameter. So, I will Google some more on
hidden field and focus on how that is done.
I have ...
<% @list_web_serv_cats.each do |category| %>
<!-- some html stuff here -->
<% form_tag({:controller => 'customers', :action =>
'list_services_available_at_location', :wsc_uid=>category['wsc_uid_pk']}) do %>
<%= category['wsc_uid_pk'] %> <!-- printing to view to verify data exists -->
<%= select_tag(:wsc_uid, '<option value="">Select Type</option>' +
options_for_select(@list_web_serv_types.collect{|servtype|
[servtype['wbt_description'].to_s, servtype['wbt_uid_pk'].to_i]},
params[:id].to_i)) %>
<!-- @list_web_serv_types uses param[:wsc_uid] to bring data from model/db
package call -->
<% @list_web_serv_types.each do |servtype| %>
<tr><td height="25px" align="left" valign="top" > <%=
servtype['wbt_uid_pk'] %> <%= servtype['wbt_description'] %> </td></tr>
<% end %> <!-- @list_web_serv_types.each end --> <% end %> <!-- form_tag
end --> </td>
<!-- next column: service category subtypes --> </tr> <% end %> <!--
@list_web_serv_cats.each end -->
Thank you,

To get a parameter submitted it should be put in a field (hidden if
necessary) on the form. Assuming you are submitting a form that is.
Alternatively if going via a link it can be put as a parameter to the
link. You need to give us a few more clues as to what you are doing.
We are not telepathic (at least I am not).
