I have two forms.  One contains a drop-down populated via lookup table.  The other contains a blank field.  I would like to be able to submit the first form with a selection and have the second form immediately open with its field populated with data passed from the first form.  i.e. I select option X --> Submit --> Form2 Presented --> Automatically populated with option X

I would like to be able to do this from within the same business process and across two business processes.  How do I do this?

Thanks
