basic form processing

I am new to PHP and have been trying without success to process a very simple form. My basic problem is trying to pass variables from a form to another page, and to echo them in a results page. I understand that the most recent versions of PHP allow you to pass user-entered form variables in the $_POST or $_GET associative arrays. I have set the "register_globals = off" in my php.ini file (under C:\winnt, running Win2000 and Microsoft IIS). When I try to submit the form, the results page is displayed without the values of the two form variables. I would very much appreciate some help with this simple problem. The basic code for my form (form_a.php) is: ************************************************************************ <HTML> <HEAD> <TITLE>Test Form One</TITLE> </HEAD> <BODY> <B> <H2>Test Form One</H2> Fill out the information below <FORM ACTION='results_1.php'> Your First Name: <INPUT TYPE="Text" NAME="FirstName"> <BR>Your Last Name: <INPUT TYPE="Text" NAME="LastName"> <BR><INPUT TYPE="submit" VALUE="Submit Data"> </FORM> </B> </BODY> </HTML> ************************************************************************ The target page that displays the form variables (results_1.php) is as follows: <HTML> <HEAD> <TITLE>Results from Form One</TITLE> </HEAD> <BODY> <B> <H2>Results from Form One</H2> <?PHP echo "Thanks $_POST[FirstName] $_POST[LastName]"; ?> </B> </BODY> </HTML> Thanks in advance, Bill
