Results are blank, or incomplete (missing columns).

 Prism is supposed to automatically update your results when the data are edited. In very rare circumstances, it can get confused. Then you see a blank results page, or one with too few columns. If this happens:

1. Drop the Change menu and choose Analysis Parameters.
2. You'll then see the dialog for the analysis. Click OK.
3. Even if you made no changes to the parameter options, Prism will recalculate the results which should now appear in full.
