I am using the following CL code to allow students to self-check contents of a table (example)
cellContent(1,3): when table7.cellContent(1,2)= “”
“”
when table7.cellNumericValue(1,2)=7.2
“”
otherwise “”
This works for finite answers, and when I enter in a range of values (for repeating decimals). The issue I am running into is if, for example, the correct answer is “1/0”, which is undefined. Does anyone know how I would write “undefined” in the validation statement?
