Mail function

Hi, I am working on a program to create a registration feature through a email notificaiton much like this list. For functional use but also for personal training. However, I can't seem to pass the variable into the mail function() ? If I echo the variable it displays it so it must be passing the variable down. If I enter in a fixed and workable email address where $email is then it works as well. So I am a little confused to this problem. I have other programs where I do this but I place the mail function within a new function(). However, when I do that it just barks back at me. Contacted my Hosting company they are investigating. Thanks in advance for your help... Here is the code.. echo "$email"; echo "Thanks for registering! <----- It does echo it. You will recieve an email shortly containing your validation code, and a link to activate your account!"; mail($email, "New Registration, www.sitename.com", " Thanks for registering on SITE NAME. Here are your login details: Username: ".$username." Password: ".$password." In order to login and gain full access, you must validate your account. Click here to validate: http://www.sitename.com/login/register.php?action=activate&user=".$username."&code=".$activation_code." Thanks! [Webmaster] "); I got the code from www.avengingsorrow.com to see all the code. Sorry about the HTML email. I am new to the list (first post) and I don't believe you can turn off HTML email in Yahoo. Thanks again in advance Zhimmy --------------------------------- Make free worldwide PC-to-PC calls. Try the new Yahoo! Canada Messenger with Voice
