Re. Conditional formating of adjacent cells but down a column

[ruthycpr]

Hello

Hope you can help

I want to colour say, C1 if A1 OR B1 > 0

I want to however repeat this down the column so ...

C2 is coloured if A2 or B2 > 0
C3 is coloured if A3 or B3 > 0

I can do it for one row, but can't work out the formula for it to apply to the whole column

When I do it, either nothing happens or each cell in column C focuses on just A1 and B1 instead of the corresponding cells in column A or B

Thanks!
