Error Uploading file to Server [RESOLVED]

[EyeTalion]

Anyone know why I'm getting this error when I try to upload?

"Object reference not set to an instance of an object."

<input id="pdfUpload"
<FORM id="_ctl0" encType="multipart/form-data" runat="server">

If Not pdfUpload.PostedFile Is Nothing Then
If pdfUpload.PostedFile.FileName.Trim().Length > 0 And _
pdfUpload.PostedFile.ContentLength > 0 Then
Const strBaseDir As String = "C:\PBSS_Uploads\"
Dim strFilename As String = _
Path.GetFileName(pdfUpload.PostedFile.FileName)

pdfUpload.PostedFile.SaveAs(strBaseDir & strFilename)

End If
End If
