Time stamp upon cell entry

Hi all,

I would like some help with making a time stamp stay as is, instead of changing everytime I open the work sheet. I have been using =IF(ISBLANK(C14), "",NOW()) .

I would like to be able to time stamp when selected cells have a value entered. As shown in attached sheet, Values will be entered into cells C2, C4,C6,C8 and a time stamp needs to be shown in cells C3, C5, C7, C9 then the same for columns 'D,E,F.....'

I am only a beginner in VBA so I would appreciate some help here if possible

regards
