Is it possible in an upgrade script to import a user's customized value lists into the upgraded datafile? I appreciate whatever advice anyone can give me, thank you.

not programatically using FMP's value lists... If you use tables and fields (the preferred method) then you can import export them.

when you setup a value list and you hesitate to click the edit /other option then ask yourself if you need to capture modified values should you need to upgrade. Then explore other methods for generating and maintaining value lists.

- One option however is use some scripting and the design functions to generate a global field that can grab all your value lists and contents and import that field in to your new solution, you will have to manually setup / copy /paste values in your new solution.

Or use the DDR report to grab values from previous version.

Thank you for your help. I'm glad it wasn't out of ignorance that I've been customizing people's upgrades to include their value lists.
