Are there multiple text fields for the values?
Or, are the values entered like:
1234567
OR
1, 2, 3, 4, 5, 6, 7

This isn't tested.. But I think this is what you mean..
<?php
function display($x)
{
$sum = (int) 0;
foreach($x as $xs)
{
$sum += $xs;
}
return $sum;
}
if(!isset($_POST['submitted']))
{
echo '<form method="post" action="">';
for($i=0; ($i < 10); $i++)
{
echo '<input type="text" name="values[]" id="textfield" /><br />';
}
echo '<input type="submit" name="button2" id="button2" value="ADD" />';
echo '<input type="hidden" name="submitted" value="TRUE">';
}else{
$values = $_POST['values'];
echo display($values);
}
?>

Your problem looks like this:
You cannot have your text fields with id's such as "1", "2", "3", "4" etc..
You need to pass them as an array, so in your html just have values[] this implies that there is an array of fields.
You can then pass this array into a function to calculate the values.
Hope this makes sense.
