Conditional formatting: One cell based on the value of another

Hi all,

I am attempting to apply conditional formatting such that cell B3 is green if it is greater than or equal to cell B2, and red if less than cell B2. Then to apply this conditioning across the row of data (i.e. C3 >= C2 green, C3 < C2 red; D3 >= D2 green, D3 < D2 red; E3 >= E2 green, E3 < E2 red ... etc.).
Needs to be formatted such that if I change the value in cell B2, the colour of B3 is automatically updated.


Please find attached an example worksheet.


Thank you for your time and assistance.
