I want to make the 4 droplist menus required if a user selects an option with an id of "26" from the Modality menu named Mod_ID. These are not to be required if the user selects any other option from that menu.
Any idea on how to help??????

This is an classic asp page & I am running sql server 2000.


<b>Modality:</b>&nbsp;&nbsp;&nbsp;
<select name="Mod_id" id="Mod_Id" class="formtxt" required>
<%Dim RS_ModCat%>
<%SQLModCat = "Select * from vw_Active_Modalities where clnum='" & clid & "' order by Mod_id asc"%>
<%Set RS_ModCat = Server.CreateObject("ADODB.Recordset")%>
<%RS_ModCat.Open SQLModCat,adoCon, adOpenForwardOnly%>

<%Do until RS_ModCat.EOF%>
<Option value="<%= Getfield(RS_ModCat,"Mod_ID")%>">
<%= Getfield(RS_ModCat,"Mod_Desc")%>
</Option>

<%RS_ModCat.MoveNext%>
<%Loop%>
</SELECT>
<%Call Selectbox("form1.Mod_id",GetField(RS,"Mod_id"))%>

Droplist 1:
<%CreateDropList "rapport_leader", "SELECT id, name FROM luClient_Participation Where cat_id='R_L' ORDER BY id", Getfield(RS_cpn,"rapport_leader"), true%>
Droplist 2:
<% CreateDropList "rapport_members", "SELECT id, name FROM luClient_Participation Where cat_id='R_GM' ORDER BY id", Getfield(RS_cpn,"rapport_members"), true %>
Droplist 3:
<% CreateDropList "client_respect_leader", "SELECT id, name FROM luClient_Participation Where cat_id='R_L' ORDER BY id", Getfield(RS_cpn,"client_respect_leader"), true %>
Droplist 4:
<% CreateDropList "client_respect_others", "SELECT id, name FROM luClient_Participation Where cat_id='R_O' ORDER BY id", Getfield(RS_cpn,"client_respect_others"), true %>


Thanks
