This message means that you are using a search form that is too old.
This can be caused by;
- Using the Revise Query button and then leaving the resultant search page for an extended period of time - only use Revise Query when you are ready to do another search
- Using your browser back button to go back to the search form - always use the Revise Query or New Query button.
- Using a saved copy of the search page.
- This won't work - you must use the page from the server every time
- Your browser may have incorrectly cached a copy of the search page.
- Your ISP's caching proxy may have cached a copy of the search page.
Please note that none of the causes of this are anything that FreeBMD can fix for you. |
