Add the property Rate to the first form in design mode. (Form menu, New Property...).

Modify the Init method of the second form to accept a parameter, and add a property to this second form. In the Init method, store the parameter into this new property.

Init (2nd form):
LPARAMETER toCallingForm
this.CalledBy = toCallingForm

Pass the object reference of the first form to the second form when it starts. I assume you're doing this from a button on the first form?

DO FORM ordersupp WITH thisform

Now, in the ordersupp form, you can reference the Order form's rate property like this:

thisform.CalledBy.Rate

Hope that helps.
