Conditional formatting date based in another column

[seventhprophet]

I am trying to create a conditional format that modifies cells in column "O" based on a date listed in Column "C". (todays date greater than 30 days from date in C).

Its easy enough to create a conditional format that does this, but I am not sure how to do this without making a separate formula for each row, IE: O5 checking C5, then another formula having O6 check C6, is there a one formula solution? or am I creating 200 separate formulas?

the one formula will work for the enter range selected
in conditional formatting

not 100% certain what you want to do
