adding total to numeric variables
Jul 22, 2021
I have a quiz question where the correct answer will be the sum of three numeric entry fields - Sphere_Entry, Cyl_Entry and Axis_Entry. there is a fourth numeric entry field which is Total. The triggers look like this:
- Set Sphere_Entry equal to the typed value when Sphere_Entry loses focus
- Add variable Sphere_Entry to Total when Sphere_Entry loses focus
This is repeated for the other two numeric entry fields.
When I test the slide, the numeric entry field Total stays at "NaN"
I am sure I got this kind of interaction working in another project, but I don't remember how...
