Have you done the following:
In Forms Mode, the left pane will have red verticle lines on forms that contain errors.
When clicking on the red error button at the top, a box in the right pane will appear stating the form and the nature of the error. The form itself will also appear and any errors will be highlighted in red and the specific cell will be highlighted in blue. After making the correction, clicking on the down arrow at the right will cause the next error to be highlighted. After completion, clicking on the red error button will remove the box.
