How do I reference the same cell as I move through range of cells.

[Guest]

I want to refence the same cell as I copy the initial range of cells further
down the page. Two of the cells referenced in the formula need to change,
but I need one to stay constant:
=IF(AND(C4>C121, C5>C122), 500, "n/a")
C4 and C5 need to change as I copy to new areas, but C121 and C122 need to
be constantly referenced.

are you thinking of absolute reference

for .e.g

$c$121 and $c$122
