Default Problem executing code

I have an ASP.NET 2.0 web application. This application has a command button that triggers some code to happen. It works on my development box; but, when I deploy to my test server, it does not appear to execute. The page appears to just repost. I included some Response.Write statements to use for debugging and none of them are displaying on the reposted page. The code is posted below:

protected void btnExecute_Click(object sender, EventArgs e)
    {
        String strPath;
        Microsoft.Office.Interop.Excel.Application objExcel = new Microsoft.Office.Interop.Excel.Application();
        Microsoft.Office.Interop.Excel.Workbook objWorkbook = null;
        Object missing = Type.Missing;

        if (Page.IsPostBack)
        {
            Response.Write("Button clicked");
            try
            {
                connProviders.ConnectionString = SqlDataSource1.ConnectionString;
                SqlCommand cmdReports = new SqlCommand();

                cmdReports.Connection = connProviders;
                cmdReports.CommandType = CommandType.StoredProcedure;
                cmdReports.CommandText = "GetReports";

                SqlDataAdapter daReports = new SqlDataAdapter(cmdReports);
                DataSet dsReports = new DataSet("Reports");
                Response.Write("Fill dsReports");
                daReports.Fill(dsReports);
                Response.Write("dsReports filled");

                foreach (ListItem l in lstProviders.Items)
                {
                    if (l.Selected == true)
                    {
                        foreach (TreeNode pn in trvReports.Nodes)
                        {
                            foreach (TreeNode cn in pn.ChildNodes)
                            {
                                if (cn.Checked == true)
                                {
                                    foreach (DataRow d in dsReports.Tables[0].Rows)
                                    {
                                        if (cn.Text == d["NodeName"].ToString())
                                        {
                                            strPath = d["FileLocation"].ToString() + l.Text + @"\" + d["NodeName"].ToString() + @"\" + l.Text + " - " + d["ReportName"].ToString() + "." + d["ReportType"].ToString();
                                            if (File.Exists(strPath))
                                            {
                                                try
                                                {
                                                    switch (d["ReportType"].ToString())
                                                    {
                                                        case "xls":
                                                            Response.Write("Made it to Excel Activation");
                                                            objWorkbook = objExcel.Workbooks.Open(strPath, 1, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
                                                            Response.Write("Opened Excel object");
                                                            objWorkbook.PrintOut(missing, missing, missing, missing, missing, missing, missing, missing);
                                                            Response.Write("Printed Excel object");
                                                            break;
                                                    }
                                                }
                                                catch (Exception DocEx)
                                                {
                                                    MessageBox.Show("Problem with file " + strPath);
                                                }
                                                finally
                                                {
                                                    if (objWorkbook != null)
                                                    {
                                                        objWorkbook.Close(0, missing, missing);
                                                    }
                                                }
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
                objExcel.Quit();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
        }
    }

I'm fairly new to ASP.NET and am stuck. Any help/guidance is much appreciated. Thanks in advance.
