There is no such thing as the percent in news fader!
I think you have mistaken the news fader width with the table width in the Style Template. You can set the table width to 100% in the Style Template, but for the news fader width, it depends or your screen resolution, you have to set it to fit it in the table, therefore, a preferably small number. You news fader has a transparent gif image, and the width of this image is changed accordingly to the number of pixels you define in the News Fader Setting.
