Hi Rich

That does not seem to have anything to do with VMP.

If you have a data entry grid on a form, when the user clicks save, the form will order the grid to delete any rows it considers blank.

I am guessing it is some trigger in the MySQL database and would eliminate that possibility by testing outside of VMP.
