Hello!
Could somebody help me with this.
When I create recordset and run query :

<% Dim intCategoryID, oNew %>

<SCRIPT LANGUAGE = &quot;VBScript&quot;>

Sub listBox_onChange()

<%Set rsSubcategory = connST.Execute (&quot;SELECT SubcategoryName FROM Subcategory WHERE CategoryID = ‘” & intCategoryID & “’”)
<%Do While Not rsSubcategory.EOF %>
Set oNew = document.createElement(&quot;&quot;)
form1.selEquipment.add oNew
oNew.InnerText = &quot;<%=rsSubcategory(&quot;SubcategoryName&quot;)&quot; <%rsSubcategory.MoveNext%>
<%Loop %>
End Sub
</SCRIPT>

The problem is that it cannot see the variable intCategoryID in a query string and does not populate another list box, but if I substitute ‘2’ instead of CategoryID it works well. The variable is working and displayed in the test label. Why? After all, can I create a recordset in subroutine on call? Is it correct to run server-side script inside client-side script?

Thanks

You can combine the server side code with client code but the server side code is executed first time you access that asp page and not on the client side event.

Also you have to use a self submit model and be shure you send CategoryID on that page.
Code: 
<% Dim intCategoryID, oNew 
intCategoryID=Request(&quot;CategoryID&quot;)
%>
<SCRIPT LANGUAGE = &quot;VBScript&quot;>
Sub listBox_onChange()
<%
Set rsSubcategory = connST.Execute (&quot;SELECT SubcategoryName FROM Subcategory WHERE CategoryID = ” & intCategoryID)
Do While Not rsSubcategory.EOF
%>
Set oNew = document.createElement(&quot;<OPTION>&quot;) 
form1.selEquipment.add oNew 
oNew.InnerText = &quot;<%=rsSubcategory(&quot;SubcategoryName&quot;)%>&quot;
<%
 rsSubcategory.MoveNext
Loop
%>
End Sub
</SCRIPT>
This should be

Thank you for your response George. Actually, I have got a main page where in the left frame an asp page loaded containing two list boxes(on the same asp page). One of them populated with Categories names initially. The second list box with Subcategories names is empty. When user selects a category in Categories list box, the second list box should be loaded with appropriate subcategories. What would you recommend me in that case? Can the list boxes be on the same asp page? As I understood from you first response, the server side script esxecutes when page is loaded, but could it be reloaded without reloading page? Sorry, if I didn't get the first response.
