Question

If i create a question in a grid form say.. qn: "if price increase by the following amount, will you still buy?" options: 5% Yes No (choose either yes or no) 10% Yes No (choose either yes or no) 15% Yes No (choose either yes or no)

and i want to create an answer validation such that if a user choose "No" for 5% and choose "Yes" for 10% and 15%, it will have an error message that say ("logical error")

What would be the right code to use?

Answer 1

At the moment, there is no way of implementing this sort of validations using Forms. The only options you have is:

1. Explaining your restrictions on your form, and using an onFormSubmit event to filter out responses that do not match your criteria. Using this option however, the user is still able to submit the form and will not receive any feedback telling him his submission is not correct.

2. Using a WebApp . The idea of this one is to implement a basic form using HTML. The restrictions you described could then be verified using Javascript, and the results can be published into a Google Sheets document of your choice. This option however, will clearly take more effort. You can see an example of creating a form using WebApps here .
