The value of 'selected_group' is only assigned to the $_POST value when
the form submit action is invoked and the form is using a POST method.

So:
1. is your <select> within a <form>?
2. does the <form> have method="POST"?
3. does the <form> also contain an <input type="submit"> or onchange= to
the select?

If not, $_POST['selected_group'] will not be set and $group will be empty.
