PHP crashes at an ODBC-Query

Hi, i have following Problem: When I query over ODBC a SQL-Server-Database (on local Machine under Win2000) I don't receive any error and it works fine so far. If the field has any content, PHP works correct without any error, but when the field is empty PHP crashes.(odbc_result($result, $field)) Does anybody out there know a work around or a solution ? ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
