To perform calculations using any kind of checkbox requires a macro. A field cannot do calculations based on checkbox states. You could, however, replace the checkboxes with dropdown for fields containing yes/no responses and use fields to calculate from those.

Hi Macropod,

Yes i did try using a drop down box for different selection. I could not get it to work. If you know how to get this to work can you please advise?

Thanks
