dropdownlist not populating

[cmu_man]

I have two dropdown lists on a webform using vs 2005/asp.net 2.0. The first is populated via an sqldatasource. The second dropdown list is populated via a second sqldatasource with a where clause based on the selected value of the first dropdown. In visual studio the population of both dropdowns work fine but when I publish to IIS only the first dropdown is populated. At this point I am out of ideas. Any suggestions would be greatly appreciated. Here is the source code. <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> Untitled Page
