Error message different than Context.Server. GetLastError.Me ssage

[tshad]

I have an error routine in my Global.asax that gives me a different message
than asp.net when you let it give you the error page.

My error routine looks like:

*************** *************** *************** **********
Sub Application_Err or
Dim objMail As New MailMessage

objMail.From = "tf*@ftsolution s.com"
objMail.To = "tf*@ftsolution s.com"
objMail.Subject = "Error at Web site"
objMail.Body = Request.Path
objMail.Body &= vbNewLine
objMail.Body &= Context.Server. GetLastError.Me ssage
SmtpMail.Send(o bjMail)
Context.Server. ClearError()
End Sub
*************** *************** *************** ***

The message sent to me is:

/development/staffing/SkillsTestDispl ay.aspx
External component has thrown an exception.

The page that asp displays is:

*************** *************** *************** *****
Description: An error occurred during the compilation of a resource
required to service this request. Please review the following specific error
details and modify your source code appropriately.

Compiler Error Message: BC30451: Name 'Global' is not declared.

Source Error:

Line 34: Sub Page_Load(sende r as Object, e as EventArgs)
Line 35: dim temp as string
Line 36: temp = Global.tom()
Line 37:
Line 38: response.write( "temp = ")

Source File: c:\inetpub\wwwr oot\development \staffing\Skill sTestDisplay.as px
Line: 36
*************** *************** *************** *************** ********

Why don't I get the error:

Compiler Error Message: BC30451: Name 'Global' is not declared.

The message that an exception was thrown doesn't tell me anything.

Thanks,

Tom
