**Rozmere**My form is designed for our printing services, since the final product requires the entry of several criteria (size, weight of paper, color of printing, duplex, finishing, quantity, etc.) I want to gather numeric values based on these categorized selections and then calculate a rough estimate from them. How do I generate numeric values from non-numeric entries?
