Thanks, ASp - ew, but I am finding it buggy trying to get around that site (eg, "Microsoft VBScript runtime error '800a005e' Invalid use of Null
/journals/includes/string_utils.asp, line 92 ")

I haven't managed to even get an abstract of the actual article, or even subscription details for an individual. Bing, do you get the paper or online version, or both? If online, is it bugridden to use? Do you have any detail of the author or date or title of the article?
