When I insert a new row in the middle of a chart I would like for two of the
formulas in the cells to carry over. At the moment only one of them does.
Here are the formulas:

=IF(G136=0,"", G136-F136) <- Carries over
=IF(OR(H136=0, G136=0),"", H136-G136) <- Does not carry over

How can this be accomplished? Thanks
