This error is probably due to a javascript error. If you are sure that the pages are exactly the same, I would also check the browser versions (SP) to see if they are the same. Nevertheless, the error should probably be fixed. Do a view source and look for any string in javascript that does not have a properly closed quotation mark. hope this helps, sivilian

i though so..... I wanted do this using Page Load or Refresh, but decided, that it wouldn't be effective...

Both of our solutions will work just fine. Using session variables, however, could lead to scalability problems in the long run. It's best to try to avoid them as a good practice. Michael Flanakin Web Log
