Hi Mike,
I assume your problem is that when you hit a blank column, you get an
error in your running total. If so, try changing your formula to
=IF(AND(E18,F17),E18+F17,0). Zeros can be made invisible by selecting
tools-options-view and unchecking the zero values box.
[If you also additionally want to hide the totals in empty columns, you
can use conditional formatting to achieve this, but I don't read this as
your requirement]
