[PHP-INSTALL] Problem with AddModule line?

[Deadly Earnest]

Sorry about this I'm doing something stupid, I'm sure, but I'm afraid I can't see what. I've searched in the mailing list for similar problems and there were a few but none provided me with an answer.

I installed PHP 5 as Per the instructions in install.unix.php on the PHP site.
I've installed Apache/2.0.53 previously on Linux Kernel 2.4.21

There's a few lines to add to the httpd.conf file the first of which 'LoadModule' goes fine:
LoadModule php5_module        modules/libphp5.so

After that the instructions say to add an 'AddModule' command the instructions being:-

And in the AddModule section of httpd.conf, somewhere under the ClearModuleList, add this:

There are no AddModule commands in my file! And there's no
sign of ClearModuleList I've searched the file and to no avail.
When I do add the AddModule line:

AddModule mod_php_5.c

I get an error when I start the Apache server:

Syntax error on line 236 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'AddModule', perhaps mis-spelled or defined by a module not included in the server configuration


Can anybody help? When I remove the line the Server starts fine and PHP seems to be working
fine. The only problem that I'm having is that I've copied an example out of a book which
passes variables from a html page to a php script and it fails.

The html page has a form:

<form METHOD="post" ACTION=""

<p>Value 1: <input TYPE="text" NAME="val1" SIZE=10></p>

<p><input TYPE="submit" NAME="submit" VALUE="Calculate"></p>
</form>


In the PHP Script I simply try to print the value:

<?PHP echo "Value 1 is $val1";?>

Is this error in transfering the variables from the HTML Page to
the PHP Script because of my failed AddModule line?

Thanks a million in advance for any help
