Can anyone help with the code for inserting actual input data in the body of the email, such as:

Name: Some name
Email address: some@email.com
Message: Message text...javascript:emoticon(':wink:')
Wink

Find this are of the code:

PHP Code:

$message.="\n";
$message.=$yourmessage;
$message.="\n"; 


Change it to something like this:

PHP Code:

$message.="\n";
$message.="Name: $name";
$message.="\n";
$message.="Email Address: $youremail";
$message.="\n";
$message.="Message: $yourmessage";
