I'm a newbie to FileMaker, so I apologize in advance for my ignorance.
I have a table of donations and I want to summarize the donations by user and export the donor ID and the donation total.
I have created a summary field, called Total Donations.
In my script, I take the following steps:
1. Enter Browse Mode 
2. Go to Layout ["Donation Report" (Dontations)]
3. Sort Records, with sort order of "Donor ID" and Reorder based on Total Donations
4. Export Records [No dialog, "donor_test", Macintosh] Group by: Donor ID Field export order: Donor ID, Total Donations]
When I do this as a layout, with no Export Records, I can see the sub summary value along with the Donor ID, but when I export, all I get is the Donor ID.
I think I am following the instructions, but obviously, I'm not.
Any ideas or insights?
