add more people form, stumped

[mwarren77]

I have a form that spans 3 pages.  I am completly stumped and know the answer is right there.

Form 1 collects vehicle information.  They can add another vehicle by clicking a textbox.  Up to 5 vehicles.  Form 2 is the same but for drivers.  The 3rd page asks for more info and has to put the driver to the vehicle. 

 

I have it setup as 1 page which controls which external page to include per step using switch statement.  I also have a simple

 

foreach($_POST as $key => $val){

$_SESSION[$key] = $val;

}

 

and build a session variable like =>

if(isset($_POST['']) $_SESSION['driver']['4'] = $_POST[''].'||'.$_POST[''];

 

For some reason I am not able to do a foreach $_SESSION or even a echo $_SESSION['driver']['4']

statement or
