Contact form Not Working Keeps Giving Me Array

So I have this contact script which works great in firefox but whenever anyone tries it in ie 7 or 8 the plan always returns array and for the life of me I cant figure out what I did wrong. Any help would be greatly appreciated.

<?php

    $city    = $_POST['city'];
    $state    = $_POST['state'];
    $zip    = $_POST['zip'];
    $plan   = $_POST['plan'];
    $verify   = $_POST['verify'];
