VS 2012 field not found

When I look through the object browser I can see the field is there but when I debug my code it throws the error "field not found"

Has anyone had any issues with this? This last line of my code is where the error is thrown.

Public Sub btn_LoadScript_Click(sender As Object, e As EventArgs) Handles btn_LoadScript.Click
Try
M3Script = New MILLCOMPANYLib.CScripting
Dim CoCode As String = cb_COID.SelectedItem
Dim script As String = M3Script.vbscript
