I am using a simple excel credit/debit worksheet that is auto totaling in the last column. I have 5 or 6 entries a year and I would like to leave a blank row between years for grouping. When I leave a blank row the auto total function doesn't work, is there any way to correct this? My curent formula is:

=IF(ISERROR(IF(OR(D13,E13),((F12)+D13-E13),)),"",IF(OR(D13,E13),((F12)+D13-E13),))
