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);  
    }


?>

first input how many textfield you want
then click ok

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.
