Problema con Class FileUpl...

[j_fco]

Hola amigos, estoy haciendo una administración para que los usuarios puedan subir imagenes dentro de un catalogo, a la hora de hacer el Update de la imagen, me marca el siguiente error:

Microsoft VBScript compilation error '800a03ea'

Syntax error

/Admin/categorias/imagenes/Upload.asp, line 16

Class FileUploader
^

La verdad no entiendo el porque del error, se supone que es una clase ya definida, a continuación les pongo el codigo del UPLOAD.ASP

Files.RemoveAll()
Set Files = Nothing
End If
If IsObject(mcolFormElem) Then
mcolFormElem.RemoveAll()

End If
End Sub

Public Property Get Form(sIndex)
Form = ""
If mcolFormElem.Exists(LCase(sIndex)) Then Form = mcolFormElem.Item(LCase(sIndex))
