Are you trying to create a value list? (Used to populate a drop down list or pop-up menu)
Or are you trying to list a particular group of records so that you can view/edit/print/other action ?
Nothing complicated here: from a master list (1st. name, LastName, address, ......e-mail) I want to create
a new Table (or list, oe database) of records which have the e-mail field empty.
No pop up or other calculated complexities here.
From thisnewly created list I want to print labels for snail-mail envelopes.
You can do that with a script or by hand:
Select a layout where the email field is accessible.
Put an = in that field
Perform the find
You now have a found set of all records where the email field is empty.
Switch to a labels layout based on the same table, preview and or print your labels.
