Richard... I created a form so I could track all the Sales Commissions that had been paid and the ones that still needed to be paid.  I used a Sum Control Source in the Form Footer as you instructed in Video 4 to get the column totals (Total Contracts Amount, Total Expected Gross Profit, Total Actual Gross Profit and Total Commissions Paid). Everything seemed to be working fine last week.  Now this week, I open up the form and these fields are not working anymore.  All the fields within each of the records are fine, but I just can't get anything in these footer totals.  And it's not even giving an error or anything.  They're just blank.  I checked to make sure they were brought to the front, in case the background was accidentally brought in front of them, but that didn't do it.  I checked to make sure the Visible property was set to Yes.  What other things could I check to make sure these show up again?
