Agreed @itonewbie . I was concerned with the error checking. If its left unchecked and "no" is auto default, Im content. If Sch 1 is present, then error will occur (if I fail to check). If no Sch 1, "no" will be default so no error is necessary. It will be up to us to check the box for yes responses. 

I hope that makes sense. 🙂
