Fancy Checkboxes includes any (numbers) that you happen to list in the options in calculations.

Don't know why? Mabe someone can answer this.

So I add Fancy Checkboxes, and made calculations of all checked. (also made separate values for each option). Problem is that when calculated, the calculation not only adds up the "Values" but also includes the values of any numerical numbers you add in the original options. Why?

Unfortunately, the option to assign calculation values is not available for the Fancy Checkboxes widget.

The calculation values should be fine on the basic fields. If you are having calculation issues using basic fields, please provide us with more details.
