I'm running Sage ACT! Pro 2011 Version 18.104.22.168, Hotfix 1
I'm starting to track which advertising source generates each sales lead. Normally the Referred By field should be a dropdown menu. In my case it's just a gray box that cannot be edited in any way. You can't even type data into it.
I have gone to the define fields section to try and "redefine it," but everything seems in order. What could be wrong here? I really need that field.
