Simple question.... is there a way to keep a reference cell in another cell absolutely fix?

Have this real case: L33 depends on the cell H36, which itself is the last available data of a series. Now, if I insert one row when in H36, that cell obviously shifts down to to H37. L33 now depends on H37... but i still want to depend on H36 with every row I add!!

Driving me crazy

Thanks
