Hi Lisa
If you're using the Checkbox from the Form toolbar, right click and go to Format
Control.
Under the Control, you can link to a cell, select a cell "Z1" just for
illustration, you can pick any empty cell. That can be visible or not but it
will return "True or False".
Now the cell that will return a value, just type =if(Z1=true,1.0,""),Remember to
change Z1 for the link cell.

can then add the values together from
