Re: Passing parameters between forms

You dont have to have the parameters defined in the calling form.

In the called form, however, you must have them defined. Forms will assign values to them when the the form is called, so all you have to do in the called form is to reference them like :PARAMETER.DZ. That is how it works in Forms 4.5 at least.
