That won't work. Variables are scoped to procedure and your form are no 
program, even if 50 forms are onscreen waiting for user entry, no 
programm is running. Every private and local variable would be out of 
scope and public ones will overwrite each other forms variables. 
Just create custom properties of the form, that's what encapsulation is 
all about, each instance of the form has its own set of properties.

Don't need that.
just:
f=new form()
f.myprop="whatever"
f.onopen={;msgbox(form.myprop)}
f.open()

Most of us have problems to get the needed time since we need to get 
accustomed to this new stuff too.<G>

This is executed in the Combobox context. THIS means the combobox which 
_has_ _no_ rowset! so checking the fields array of a nonexisting rowset 
generates this error.

use FORM.rowset..... instead.

Don't use PUBLICs _ever_.<G>
Just:

  Procedure Form_OnOpen
  form.selectedGroup="MY group"

Yes, you mix up THIS and FORM, they are interchangeable _only_ for form 
events, in control events, THIS means the control that triggered the 
event.

We are _all_ newbees as far as VdB7 is concerned, it's only out a couple 
of months.
