I'm working on a form that will allow my clients to customize their wedding invitation order and allow them to add on a variety of different options. I'm looking to create a field that will dynamically populate if someone chooses "yes, please" under "Add Envelope Liners". If so, I want the quantity of envelope liners to match the quantity of invitations chosen (+additional envelopes if they've chosen to add those). Here's where it gets a little tricky...there is different pricing for solid liners or pattern liners. So the query also needs to pull the correct quantity-based pricing depending on if the customer chooses pattern or solid. Is this possible?
