I have a second part of a form, where the details for the first part are already in the database, and now I need to add the managers comments.
So can you use a WHERE clause when using INSERT as below:

Code:
$sql = mysql_query("INSERT INTO hazzard (Name, Employerofperson, Contactphone, Location, DateOccured, ProductionZone, NearMissDetails, Anyimmediateactions) WHERE UniqueIdentifier=".$report_ID." VALUES ('".mysql_real_escape_string($_SESSION['name_A'])."','".mysql_real_escape_string($_SESSION['companies_A'])."','".mysql_real_escape_string($_SESSION['numbers_A'])."','".mysql_real_escape_string($location)."','$current_time','$ProductionZone','".mysql_real_escape_string($detail)."','".mysql_real_escape_string($feedback)."')") or die (mysql_error());
