I have a form and a subform. The subform is set up to allow numberic data to be entered in several fiels to answer certain questions. Each column has a running total at the bottom. I have a calculation at the bottom of the subform to calculate the totals of the columns. I need to average this total and then have it write to the main form and then link to another form. Can anyone help me with an expression. I have looked everywhere.

Use the expression builder. It will keep things straight for you.
