Hello, I am trying to adapt the Amazon SPL Linky for a friend who is a patron of the Tulsa City-County Library. I am no coder, I just tried to modify the variables at the top, but I get an error from userscripts.org when I ty to install the script. : <html><body><p> We are very actively developing userscripts.org and something broke. Sorry! </p> <!-- undefined method `+' for nil:NilClass --></body></html> The script is at: http://ashkev.weblogs.us/atccllinky.js Any help would be greatly appreciated. Thanks, Kevin Smith -- Kevin Smith Assistant Director Cass District Library AND The Fiddling Librarian: http://ashkev.weblogs.us
