[Getting 'Notice' messages, but why ??]

I have like 4 notice messages:
Notice: Undefined index: CName in c:\Inetpub\wwwroot\Test\phpDatabase.php on line 17
Notice: Undefined index: CEmail in c:\Inetpub\wwwroot\Test\phpDatabase.php on line 18
Notice: Undefined index: CTextArea in c:\Inetpub\wwwroot\Test\phpDatabase.php on line 20
Notice: Undefined index: CFlag in c:\Inetpub\wwwroot\Test\phpDatabase.php on line 21

But I've defined the varibels before:
17: $NewName = $_REQUEST["CName"];
18: $NewEmail = $_REQUEST["CEmail"];
19: $NewDate = date('Y-m-d G:i:s');
20: $NewMessage = $_REQUEST["CTextArea"];
21: $flag = $_REQUEST["CFlag"];

What can be the problem ??
(The code is working...)


Thanks !

[Problems with sending in PHP code]

Hey guys,

I'm very new with PHP.
I'm trying to define a value that I've read from MySql DB, as an email link.
(the 'name' will be a link to the 'email', both are values from DB).

Something like this:

<TD><a href="mailto:",$row['email'],">",$row['name'],"</a></TD>

Well.... It's wrong. But why....? I have no idea how to write it currectly.

Will apriciate any help !
Thank you,

Ronen
