and add $done="TRUE"; here

Oh, you shouldnt have the exit, and you should hae an if/else... if you want to keep running hte page after the error for not filling in the title

<title>hotnews</title><?php//LAST UPDATE// 27-09-2007include("config.php");$error = "";  if(isset($_POST['submit']))  {//begin of if($submit).	  // Set global variables to easier names	  $title = $_POST['title'];	  $text1 = $_POST['text1'];	  $text2 = $_POST['text2'];			  //check if (title) field is empty then print error message.			  if(!$title){  //this means If the title is really empty.					 $error = "Error: News title is a required field.

you'll need a seperate variable for each, a variable can't store multiple strings and automatically know which you want(try $title_error, $text1_error, $text2_error)

getting close, but now the "else" statement only works for the last error.Change this else:

	  else	  {		 //run the query which adds the data gathered from the form into the database

to this
	  if($error = "" && $error1 = "" && $error2 ="")	  {		 //run the query which adds the data gathered from the form into the database
