First question is why do you need to pass it through like that?
> it is not coming across as an array so the foreach is throwing an error
I assume it always has a ',' in it if you only choose one box.
if (strpos($_POST['selectedcontactlist'], ',') === false) {
// no boxes were selected - or at least there is no comma.
die();
}
// turn it into an array
$selected_contact_lists = explode(',', $_POST['selectedcontactlist']);

No need to do that either, just make the form variable an array:
<input type="checkbox" name="selectedcontactlist[]" value="X">
The [] turns it into an array which php can then process automatically
as an array.
You can check that some checkboxes are ticked using an idea similar to this:

Though I'd just either set a flag or counter instead of a message when
you find one that is checked.
If you're just checking that any are checked, as soon as you find one,
return true out of the function.
