I can't tell for sure from the image provided, but it looks like your "rows" of data are from multiple fields in the same records when you should instead have a set of multiple records such that each row represents a different record.
Thank you - excuse the novice, but can you tell me how I would do that? I need to be able to sort or find on any of the column headings or any combination.
You'll need to learn more about how to design FileMaker layouts and the tables of records on which they are based. I can provide a few hints, but this is no substitute for spending time with some training resources learning more about how this system works.
Go to Manage | Database | Fields and delete all the field definitions except for the fields used for the first row of fields shown in your screen shot.
Then either use table view or list view to view your data. To add a new row of data, select New Record from the records menu or click a button set up to perform the same task.
If you want to use list view (the better option in my opinion), you'll need to enter layout mode and edit this layout to reduce the height of the body layout part to just barely the height of your single row of fields.
