Invalid Page numbers

I have a large document with over 100 pages. I have created two master pages that assign odd and even page numbering. When I go to print the document it automattically shows SEC1:235, and will not let me select a range to print from. I do not want to print all 235 pages at once, but I do not know how to resolve this. When I try to enter in a range, for ex. 26-120, it tells me the page numbers are not valid. Help!
