$chkfries = $_POST['chkfries'];
$chksoda = $_POST['chksoda'];
$chkshake = $_POST['chkshake'];
$chkketchup = $_POST['chkketchup'];

print <<<HERE

ChkFries: $chkfries <br>
ChkSoda: $chksoda <br>
ChkShake: $chkshake <br>
ChkKethcup: $chkketchup <br>
<hr>

$total = 0;

if (!empty($chkfries)){
  print ("You chose Fries <br> \n");
  $total = £total + $chkfries;
} // end if

if (!empty($chksoda)){
  print ("You chose Soda <br> \n");
  $total = £total + $chksoda;
} // end if

if (!empty($chkshake)){
  print ("You chose Shake <br> \n");
  $total = £total + $chkshake;
} // end if

if (!empty($chkketchup)){
  print ("You chose Ketchup <br> \n");
  $total = £total + $chkketchup;
} // end if

print "The total cost is \$$total \n";

?>

</body>
</html>

Sorry for the inconvenience...

What was your "last problem"?

Also, you're using £total instead of $total.

It might also be better to store the price in the script so people don't change it before submitting.

my last proble was

firstly:

Code:

<html>
<head>
<title>Font Choices</title>
</head>
<body>
<center>
<h1>Font Choices</h1>
<h3>Demonstrates how to read HTML form elements</h3>

<form method = "post"
      action = "bordermaker.php">

<h3>Text to modify</h3>

<textarea name= "basictext"
          rows= "10"
          cols= "40">
Woohoo I'm acutally making a textarea. I have also been able to make
different kind of borders, with diferent fonts and sizes. How good am
I? I bet you're really impressed aren't you.So ner ner ner ner! 
</textarea>

<Table border = 2>
<tr>

<td><h3>Border style</h3></td>
<td colspan = 2><h3>Border Size</h3></td>
</tr>

<tr>
<td>
<Select name = Borderstyle>
<option vale = "ridge">Ridge</option>
<option vale = "groove">Groove</option>
<option vale = "double">Double</option>
<option vale = "inset">Inset</option>
<option vale = "outset">Outset</option>
</select>
</td>

<td>

<Select size = 5
        name = Bordersize>
<option vale = "1">1</option>
<option vale = "2">2</option>
<option vale = "3">3</option>
<option vale = "5">5</option>
<option vale = "10">10</option>
</select>
</td>

<td>
<input type = "radio"
       name = "sizetype"
       value = "px">pixels<br>
<input type = "radio"
       name = "sizetype"
       value = "pt">points<br>
<input type = "radio"
       name = "sizetype"
       value = "cm">centimeters<br>
<input type = "radio"
       name = "sizetype"
       value = "in">inches<br>

</td>
</tr>
</table>

</table>
<input type = "Submit"
       value = "Show me">


</center>
</body>
</html>

then...

Code:

<Html>
<Head>
<Title>Your output</title>
</head>
<body>
<h1>Your Output</h1>
<Center>

<?php

$theStyle = <<<HERE
"border-width:$Bordersize$sizetype;
border-style:$Borderstyle;
border-color:Red"
HERE;

print "<div style = $theStyle>";
print $basictext;
print "</span>";

?>

</center>
</body>
</html>

but that was fixed using the $theStyle = $_POST['theStyle']; coding for all variables

However, won't work this time round while using checkboxes...I'm only a beginner
