I have a simple form to print select values in an invoice table. It has 2 drop down lists and view/print cancel buttons. drop down list 1 is a list of vendors (it displaces the vendor name but also contains a vendor code). User picks and vendor and I want drop down list 2 to have only orders for that vendor. I saved the selected vendor code in a property and tried to use it in the select statement for drop down list 2. VFP says This.name or ThisForm.name can only be used in methods. I think I could declare a private variable in in init of form but I am not sure that would work and it seems very unOOPs like. What is the best way to do this?
