Facebox time delay once page load I keep getting jQuery.facebox

[James Wrest]

this is what i started with

  <script type="text/javascript"> 

    jQuery(document).ready(function($) { 

        jQuery.facebox('hello'); 

        

       

    }) 

</script> 

this is the code im using to delay

  <script type="text/javascript"> 

$(document).ready(function(){

    timeOut();

});

function timeOut() {

    var t = setTimeout("showPopup();", 3000);

}

function showPopup() {

    jQuery.facebox('hello');

}

</script> 

i keep getting safety_score.php:258 Uncaught TypeError: jQuery.facebox is not a function

im not sure what im doing wrong, the on page load works fine....
