Couldn't you write a function as well?


You can put the function at the top of your script, below the opening php tag.

PHP Code:

function checkValues($step, $agree, $page);
{
    if($step == 1 && $agree == "yes")
    {
        header('Location: ?step=$page');
    }
    else
    {
       header('Location: ?step=$page&warn=yes');
    }
} 


Where you're using the if/else or switch method you can replace it with

PHP Code:

checkValues($_POST['step1'], $_POST['agree'], $_POST['page']) 


In your first form add the HTML code below the opening form tag.

<input type="hidden" name="page" value="1" />

Add the same HTML code to all the other forms but change "value="1"" to "value="2"" and value="3"".
