the way i would do this is to have the form validation on the same page as 
the form
and when user input has been validated the require another script (keeps 
global variables)
you could try something like this

         $error_addr = "";
         //form validation
         if ($user_input == "ok"){
         $user_input_error = "<font color=red> user_input must = ok </font>";
<?php echo($user_input_error) ?>
<input type='text' name='user_input' value='<?php echo($user_input) ?>'>
<input type='submit' name='submit' value='go'>

hope this helps
