I think you have the right idea. Save your Word document as HTML. If you open it up in Internet Explorer and it looks good then you are almost there! Then in your scale response item, enter the name of the HTML file in the background field. Add parameters in parentheses to define where the HTML should be displayed. E.g.,
Code:
myworddoc.htm (l.5,t.1,w.45,h.8)
Would have your html starting half way across the screen at the top. If you have any trouble with it let me know! Be sure to check out the section on questionnaire backgrounds in the user's guide for more detail.
