Hide row when only this column is fill ?

Hello

currently i have done up with a vba script when i select this field the box will appear and hide if is not the selected value, however after some improvement to the vba script now i want that the user if they didnt select the value in that column the field will not appear till they have selected the value in the column

here my example file i have attached

I would like to continue to hide when "Donation to Charity" or "Dumping/Destruction" is selected when my column B of that row is not field in or selected
