mega formula

Hi ,
I have this table from column e7:I38 which has a mega formula in each cell and the source file is at z4:AM36,the main work of this formula is as follows ---
for example if we look at cell e7 it will check for month C7 in range AG4:AG32 and year C7 in Ag4:Ag32.Now my requirement is to include an or formula which check range AH4 :AH32 if the cells in AG4:AG32 are empty.As you can see in the sheet some cells after AG19 are empty,here its going to check for cells in AH as well.
