Previewing Your Program as You are Editing It🔗
As you're making changes to your program, you might want to see how those changes look on the screen. To do that, locate and click the "Preview" button at the top of your edit screen. You'll then see the program as an actual user would see it.
To return back to editing, simply click "Edit."
All these preview runs will show up on your data page as "test": they will be in a lighter font color and will have a small icon on the far right that says "test" instead of "data." When you download a CSV of your data or look at the answers users gave to your questions, you'll ONLY see the real data, not data from your preview runs. If you've made a mistake, you can easily toggle any run from "test" to "data" and vice versa. This helps cleanly separate data generated during previewing from real data produced by people using your program.
Previewing Versus Running a Program🔗
As an editor, you can "preview" your program as we described above, or you can "run" your program. Both options will allow you to see your program in its live form, as an actual user would see it. The only difference is how your answers to questions in the program and path through the program is recorded in the data. In a preview run, your data will be stored on the data page as a preview, and will not appear in downloaded copies of your data. In a regular run, your data will be stored on the data page as data, and will appear in downloaded copies of your data. On the data page you can toggle each run between "data" and "test" to change how it is recorded in the CSV.
