I am asking a demographic question on race. If the participant selects "biracial/multiracial" I would like a text box to appear that allows them to specify the races. Is this possible?

Also, is it possible to display the word "none" as a choice in scale response? Currently there's a space so it looks like " none" but I was wondering if there were other solutions. Thank you!

I am using MediaLab 2006.
