weird session setting problem

This is the output of me entering a phone number in to my 3 field area. It works if I echo each post variable, but when I try to echo my session it displays the above.

 

The form piece:

<input type=\"text\" size=\"3\" name=\"phonenumber1\" value=\"$_POST[phonenumber1]\" />
<input type=\"text\" size=\"3\" name=\"phonenumber2\" value=\"$_POST[phonenumber2]\" />
<input type=\"text\" size=\"3\" name=\"phonenumber3\" value=\"$_POST[phonenumber3]\" />

 

The session being set:

$_SESSION['telephone'] = $_POST['phonenumber1'] - $_POST['phonenumber2'] - $_POST['phonenumber3'];

Because you are subtracting each one with -

 

What do you want to do?

[aebstract]

Eh that makes sense, put a dash in between each instead of subtract?

Try using quotes around the whole thing and make it a string.

[aebstract]

	$_SESSION['telephone'] = "$_POST[phonenumber1]-$_POST[phonenumber2]-$_POST[phonenumber3]";

 

It is a string, is it not? I tried piecing it together with  . ' ' . and didn't get a result. With the above, it isn't outputting anything.
