I am not sure if I am missing something, but I am only able to enter the width on the detail size and not the height in the layout tab.  I entered the width, horizontal gap and printing directions across then down.  but the height is grayed out and will not let me enter a height?  I know I can go thru the lable wizard, but thought this would be just as easy except it wont let me add height and now I'm curious to find out why??
