6 star ranking system: how to select a rating by clicking on one of the stars

Hello again,

For my music database I set up a system of IF-formulas to turn a numeric rating into a 6 star visual. Now I want to make it possible to click one of the stars to change the rating. I understand I need to set up a macro but I am a newb with VBA. Can anyone tell me the needed code? I would also need a button to remove any rating. I attach the worksheet.

Thanks!
