I have set up a data form and have data validation rules on the various input
cells. I see that there is an option called "Ignore blanks" in the data
validation settings, which is supposed to restrict someone from entering past
an input cell without entering valid data, if the "Ignore blanks" box is
unchecked. I have tried to do this, but it does not seem to work. Please
could someone tell me what I am doing wrong?
