I am getting this error message when trying to create a JQuery image slider.

Uncaught ReferenceError:$ is not defined

Here is my NEW coding (NOTE that I have moved the script to the of the page, this was suggested by adobe.) :

$(function(){
        $('#slider').cycle({ 
        fx:     'scrollHorz', 
        speed:  'fast', 

        next:   '#next', 
        prev:   '#prev' 
    });
});
</script>
</body>
</html>

My folder path to the JS folder for my website (locally) looks like this: C:\Users\Andrew\Desktop\GCFS\JS

I am new to the coding world, but what I am trying to achieve is fairly simple. As far as I know I do not need to have a ready function and the javascript should run automatically. Thank you for your assistance!

When I tried this it also failed

<title>Green Cold-Formed Steel | Home</title> 
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script src="JS/jquery.cycle.all.js"></script> 
<script type="text/javascript"> 
 $(function() {  
   $('#slider').cycle({ fx: 'scrollHorz', speed: 'fast', next: '#next', prev: '#prev' });
}); 
</script>

The solution:

1) Use Google CDN to load jQuery

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>

2) As far as I know about the Cycle Plugin, It is compatible with jQuery v1.5-v1.7 because most of the methods were deprecated in jQuery 1.8+ . This is the reason I've used v1.5 of Google CDN jquery in point 1. Most of the examples on cycle plugin use jquery 1.5.

3) Clear Your browser cache, It is the main culprit most of the times.

4) PLease check the loading of jquery using the code below

if(typeof jQuery!=='undefined'){
    console.log('jQuery Loaded');
}
else{
    console.log('not loaded yet');
}

Major Edit:

The reason for the error is fairly simple:

You have called the cycle method before the jquery is loaded.

call cycle plugin on DOM ready..

$(document).ready(function(){
    $('#slider').cycle({ 
        fx:     'scrollHorz', 
        speed:  'fast', 

        next:   '#next', 
        prev:   '#prev' 
    });  
});
