I have a form to email program. Everything works except I can't seem to make the user's name (which is input through the form) appear on the CGI program's acknowledgement page to the user. The variable I used is called username. I  thought I could get the value of this by simply typing $username:

#within a sub-program
print "Content-type: text/html\n\n";
print<<"(ENDOFACK)";
<HTML>
<HEAD>
<TITLE>Acknowledgement</TITLE>
</HEAD>
<BODY>Thank you, $username!</BODY>
</HTML>
(ENDOFACK)


The response page that results is:

Thank you, !

Can someone help?

You probably arent defining $username anywhere, try this simple script, which should give you an idea what you need to do...

#!/usr/local/bin/perl -w
use CGI;

$cgi = new CGI;

print <<"END";
Content-Type: text/html

<HTML>
<HEAD>
<TITLE>Test</TITLE>
</HEAD>
<BODY>
END

if($cgi->param) {
    print "Thank you, ".$cgi->param('username')."!\n";
} else {
print <<"END";
<FORM METHOD=POST ACTION="$ENV{'SCRIPT_NAME'}">
Username: <INPUT TYPE=TEXT NAME=username><BR>
<INPUT TYPE=SUBMIT>
</FORM>
END
}

Also take a look at the CGI documentation ('perldoc CGI').

Thanks, Robobob. You were right. I missed out the definition of $username in my script.
