Lisa,

>You are probably confused because when you have done DO FORM in the past (rather than a class) the variable reference is automatically declared PUBLIC.

A public memvar is only created when DO FORM xyz is executed from the command window. Running a second simultaneous instance from the command window does not create a memvar.

DO FORM xyz from a button click creates no public memvars, the builtin _screen.Forms[] collection or ActiveForm properties are the only way to obtain a reference to the form instance.
