First off, you should read the free FileMaker Training Series
To your problem
In Inspector on the Data tab you see this
Make sure you have Find Mode enabled there, if not you can not use in Search Mode
Yes, find mode is enabled on the inspector,
I learned a lot from this training series, still I don’t think it answers to how to allow search by a value in a pop-up menu possible by default.
I’ll research other options then.
What kind of Value List is it? Is it based on another table that is related, then you will not have any values in the Value List
Might the popup's field have global storage specified?
You can't enter find criteria into a global field while in find mode.
It might sound a little odd, but I changed the style to a drop-down list, exited the program and restarted it again, changed the control style back again to pop-up menu and the search works now in find mode! I don’t get the logic behind this really but happy to have it working now.
Thank you Johan for taking the time replying to this. philmodjunk I’m gunna keep your last note about the global storage in mind for the future.
