Validating Custom Item Required Responses

[Don Lund]

Thanks for the clarifications. So I entered in this code throughout a number of different HTML questionnaire files. It works properely in 2, however in most of them I get the following error message:

An error has occurred in the script on this page.
Line: 8
Char: 5
Error: 'documnt.Q1norms.nr1.7.checked' is null or not an object
Code: 0
URL: file:///C:/MediaLab/Samples/Reciproc...%20%20%20.html

Do you want to continue running scripts on this page?

I get the above message whether the questions have been answered or not.

When I run the questionnaire I'm attaching, the Q1norms gives me the error messages while the demos works properely. They are both used by the questionnaire I'm attaching.
