Auto fill a cell with a colour when typing a number

Dear experts,

Herewith attached a work book for which I need your help.

What I need is;

When I type numbers in the cells from D4 to D14, E4 to E14 and so on, the particular cell should turn into "Green". All the the cells will remain "yellow" and blank until numbers are entered based on the daily cleaning of machines. When particular machine no is entered in to a cell cell, that cell should turn green(this shows that "service is done for that machine")

Select all cells, go to Conditional Formatting, New Rule..., select Use a formula to determine which cells to format, insert this formula =ISNUMBER(D4) press Format..., select Green, Ok, Ok, done.

Or Select all cells, go to Conditional Formatting, Highlight Cells Rules, Greater than..., enter 0, with Custom Format..., go to the Fill tab, pick Green press Ok, Ok, done.

Thanks a lot...
