Call to member function on non-object

[hjhawk25]

I am receiving this error- I took this code/site over from another PHP developer.

Well, which one is line 27? Double check all the variables in that line to make sure that they have been created. And second, make sure that they are objects and not some other data type.

Line 27 is this line:

if(!$this->result = $this->dbconn->query($sql))header("Location: message.php?error=sqlcmd&errno=".$this->dbconn->errno);

I am attempting to find which variable is causing it....
