The container FleetExtras_DK initializes just fine, so why can't I see it on the form?

I'm adding it at runtime, because, depending on the gcCountry parameter that's being passed to the exe, different stuff is being displayed.

BTW, this initializes ok

ThisForm.Pages1._Page2.oFleetExtras = NEWOBJECT((cFleetExtras),'USERFORMS')

but this does not

ThisForm.Pages1._Page2.oFleetExtras = NEWOBJECT(&cFleetExtras,'USERFORMS')

Why?

Anyway, here's the code:

cFleetExtras = 'FleetExtras_'+ ALLTRIM(gcCountry)
ThisForm.Pages1._Page2.ADDPROPERTY('oFleetExtras',.NULL.)

TRY 
   ThisForm.Pages1._Page2.oFleetExtras = NEWOBJECT((cFleetExtras),'USERFORMS') 
CATCH
   cFleetExtras = 'FleetExtras_DK'
   ThisForm.Pages1._Page2.oFleetExtras = NEWOBJECT((cFleetExtras),'USERFORMS')
ENDTRY

ThisForm.Pages1._Page2.oFleetExtras.Top  = 202
ThisForm.Pages1._Page2.oFleetExtras.Left = 6
ThisForm.Pages1._Page2.oFleetExtras.Visible = .T.

TIA
