I am making a list of publications as an order form and beside the name of the publication I want to add the quantity that people can fill in how do I do that?
Can you use a number field, with the publication name next to it? That would allow them to enter the number of each publication they want.
Or, you could use drop down fields, one for each publication, with the numbers 0 through 9 (or whatever your max number of copies per order would be) in the drop down. There are a lot of ways to approach it. What have you tried so far?
