Jane, putting in an empty string on the "Comment" field, instead of leaving it blank, had eluded me, thanks for that tip.
Peter, "Generate Automatic Comments" on the "Validations" tab is the setting I had been looking for, thanks for that.
All,
I also discovered that I can un-check the "Last on Line" and "Last on Cell" boxes which then enables the
"Suppress Comment" checkbox (3rd property from the bottom of the "Field" tab) which I can then checkmark! Once that is checkmarked, I can then turn "Last on Line" checkbox on.
However, check-marking "Last in Cell" will clear the "Suppress Comment" checkbox.
