Hi Tia.
a "Parse Error" is when you have entered something incorrectly. Often it's because one have forgotten to add ; at the end of a line, as in your case.
Take a look at the line:
$connection=mysql_connect("localhost", "webuser", "dbowes323") or die ("Connection Couldn't Be Established")
and on line:
$db=mysql_select_db("msds", $connection) or die ("Database Not Available For Selection")
They should end with a ; and therefore look like this:
$connection=mysql_connect("localhost", "webuser", "dbowes323") or die ("Connection Couldn't Be Established");
and like this:
$db=mysql_select_db("msds", $connection) or die ("Database Not Available For Selection");
Generally the "parse error" message also gives you a hint on which line the error is on.
