The error message told it all. Jochem was correct albiet not in the
style I prefer. I had the code in an HTML page after the header. I've
been a programmer for 15 years but I'm brand new to PHP. Anyone can make
a rookie mistake. Thanks everyone for the help. Everyone was partially
correct in assessing the problem.

I'm pasting this code from the example at php.net and getting these

$_SESSION['animal'] = 'cat';
$_SESSION['time'] = time();
// Works if session cookie was accepted

// Or maybe pass along the session id, if needed

Well, this is weird. When I copied your text and tried it myself, the
error I got was:
Parse error: syntax error, unexpected T_STRING in /Users/ericgorr/
Sites/page1.php on line 9
Now, of course, there is nothing visibly wrong with line 9
($_SESSION['animal'] = 'cat';). But, when I had my text editor show
invisible characters, there were some on that line and line 10.
Do you have a text editor that can show invisible characters?
On the Mac, the one I really like (and is free) is TextWrangler
(http://www.barebones.com/products/textwrangler/ ) and has this
capability. This may be part of your problem. Once I got rid of the
invisible characters, the example worked without any problems.
Also, are you certain there are no spaces or anything (even invisible
characters) before <?php?
Whenever I've gotten a similar error in the past, that was nearly
always the problem. You are welcome to compress the text file and
send it to me directly so I can see exactly what it contains.
Since you're a PHP rookie, to sum it up: there can not be any output
before you start a session.
When PHP interprets a file (include or otherwise) it considers anything
before <?php as HTML, so it outputs it as HTML (newlines, spaces,
whatever). So if you have whitespace before the <?php, then the PHP
interpreter outputs it, thus the output before the session_start() error.
