HI, I'm having trouble with my Resource Script

I'm codig my menu bar on the Resource Script like this:
(example)
Code:
ID_MENU MENUEX
{
        POPUP "Ficheiro"
{
              MENUITEM "Exportar", IDM_EXPORT
              MENUITEM "Clientes", IDM_ADDCLIENTS
}
}
And it's output is ok. But when I add like a new status:
(example)
Code:
 MENUITEM "Exportar", IDM_EXPORT,0, MFS_GRAYED
The menubar stops of appearing.

I'm using Dev-c++ and mingW compilator.
Why is this happening?
