unexpected T_ISSET

Hi Does anybody know what this means : Parse error: parse error, unexpected T_ISSET, expecting ',' or ';' in c:\program files\nusphere\apache\htdocs\trusctravel\index2.php on line 8 I've started using Apache on Windows 98 using PHP as a SAPI module. I was using Xitami but needed to use PHP_SELF which wasn't available in the CGI version of PHP which Xitami supports. Since using Apache my code which worked perfectly on Xitami no gives the error above. Line 8 looks like this: $DOC_TITLE = "My homepage"; Any help would be appreciated. Thanks Luke
