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?

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