Actually, it's good form to toggle the command button's Enabled value based on the form's existence - I'd do this in the button's Refresh() method. Better user interface and all.

Look at the scope of your variable "myform". If it's out of scope, TYPE() will return "U", which is not what you want. If the form you are trying to open is in function a child of the form that calls it, make it a property of the parent form - i.e. Thisform.oChildForm. Then you would have:

DO FORM someform NAME Thisform.oChildForm

and then:

IF TYPE("Thisform.oChildForm")="O" .AND !IsNull(Thisform.oChildForm)
Thisform.oChildForm.Show()
ELSE
DO FORM someformfile NAME Thisform.oChildForm
ENDIF

C'est claire? :)
