Advanced Form Validation by random additional expressions
-
Hello, I have tried to create an Advanced Form Validation by numerical addition expressions, like 6+7=13. It works for one numeric field, showing up in the form. I wonder if there is a possibility to define an array of numerical additions and accepted result and get only one numeric validation field showing up randomly in the form for validation.
Array ex:
6+7=13
12+8=20
2+14=16 … and we should get only one of them randomly for form validation before submission.
