However, in the assessor choice list, I have the option of "other" at which point, another text field pops up in the survey and the assessor can enter her/his name. I can add the ${assessor_other} field into the instance, but then I get the word 'other' before the other assessor's name. Is there a way to not include it, should the assessor_other field be filled out!?
One way is create a hidden field in your form with a if(they picked other, use other, use list). Then use that field in your instance id. You can also do this trick to store the other choices in the same field. Usually called the 3rd field trick and it has been posted a few times. Basically you have a 3rd field that you can put the list choices and other options they typed in all in one field. Makes data management later way easier.
