<html>
<body>
<form action=form.php method=post>
<input type=text name=textname>
<input type=submit value=Submit>
</form>
</body>
</html>

form.php

<?php
// $_POST[textname] is the variable

echo $_POST[textname];
?>

thanks, but not exactly what I am looking for.
Here is what I have so far. I am a newb, so am I rigth in thinking that whatever is selected to be found true in the swtch statement - those values will be stored in the $location variable??

<?php


$candis = 100;
$usadis = 200;
$mexdis = 300;
$eurodis = 800;
$asiadis = 900;
$afrdis = 850;
$ausdis = 500;

switch ($location)
{
  case 'canada' :
     echo '<p>Canada = '.$candis.' miles.</p>';
     break;
  case 'usa' :
     echo '<p>USA = '.$usadis.' miles.</p>';
     break;
  case 'mexico' :
     echo '<p>Mexico = '.$mexdis.' miles.</p>';
     break;
  case 'europe' :
     echo '<p>Europe = '.$eurodis.' miles.</p>';
     break;
  case 'asia' :
     echo '<p>Asia = '.$asiadis.' miles.</p>';
     break;
  case 'africa' :
     echo '<p>Africa = '.$afrdis.' miles.</p>';
     break;
  case 'austrailia' :
     echo '<p>Austrailia = '.$ausdis.' miles.</p>';
     break;
  default :
     echo '<p>No clue whre you are from.</p>';
     break;
}



//$location = 50;
while ($location <= 250)
{
  echo "<tr>\n  <td align='right'>$distance</td>\n";
  echo "  <td align='right'>". $location / 10 ."</td>\n</tr>\n";
  $location += 50; 
}
?>

Does anyone see what I am trying to do?

Thanks.

No, in this case, the switch is assuming the value of the variable $location to be a country name... canada, usa, mexico, etc.

If you are passing a country name into the location variable, then you would need to reassign a value to location based on the country name, then the $location variable would be set to a value to use in your while loop below...

Although, I am not sure where your $distance variable is coming from in the WHILE loop...

Try this:

<?php 


$candis = 100; 
$usadis = 200; 
$mexdis = 300; 
$eurodis = 800; 
$asiadis = 900; 
$afrdis = 850; 
$ausdis = 500; 

switch ($location) 
{ 
  case 'canada' : 
     echo '<p>Canada = '.$candis.' miles.</p>';
     $location = $candis; 
     break; 
  case 'usa' : 
     echo '<p>USA = '.$usadis.' miles.</p>'; 
     $location = $usadis; 
     break; 
  case 'mexico' : 
     echo '<p>Mexico = '.$mexdis.' miles.</p>'; 
     $location = $mexdis; 
     break; 
  case 'europe' : 
     echo '<p>Europe = '.$eurodis.' miles.</p>'; 
     $location = $eurodis; 
     break; 
  case 'asia' : 
     echo '<p>Asia = '.$asiadis.' miles.</p>'; 
     $location = $asiadis; 
     break; 
  case 'africa' : 
     echo '<p>Africa = '.$afrdis.' miles.</p>'; 
     $location = $afrdis; 
     break; 
  case 'austrailia' : 
     echo '<p>Austrailia = '.$ausdis.' miles.</p>'; 
     $location = $ausdis; 
     break; 
  default : 
     echo '<p>No clue whre you are from.</p>'; 
     break; 
} 



//$location = 50; 
while ($location <= 250) 
{ 
  echo "<tr>\n  <td align='right'>$distance</td>\n"; 
  echo "  <td align='right'>". $location / 10 ."</td>\n</tr>\n"; 
  $location += 50;  

} 
?>
