Hi Kevin,

Try. Put the code below in a program (called of "prgClass"):

DEFINE CLASS myClass as Container
	PROTECTED txt1 as TextBox
	txt2 = .F.
	
	PROCEDURE init()
		this.txt1 = CREATEOBJECT([TextBox])
		this.txt2 = CREATEOBJECT([TextBox])
	ENDPROC
ENDDEFINE

After, create the object based in "myClass" and try to access "txt1" and "txt2", thus:

* You can to do this in command window.
SET PROCEDURE TO prgClass
loMyObject = CREATEOBJECT([myClass])

MESSAGEBOX(loMyObject.txt1.Name)   && Here occur error
MESSAGEBOX(loMyObject.txt2.Name)   && Here work fine

I hope this help you.
Good luck!
