Conditional value list for portal items
Hi I'm a new user of Filemaker Pro 12. I have a database that I'm going to use to encode invoices. What I did was I used a portal for inputting the invoice items. What I want to do is when I'm choosing a product code for the invoice items it will be limited depending on the choice of what company it is going to be invoiced to. Choices will be made using a value list for the company, which is outside of the portal. How do I do this?
