If you have multiple check boxes, how do you assign a unique value to each item in the check box. For example, say you have red, blue, and yellow as check box options. How then do you assign a unique value to each color, so that when a person clicks on the color, its associated value is added to the calculation. In Excel, this would be done with an IF,THEN function. |
