Please Help… Simply cannot get this working

Hello, I am a Web Developer and I am fairly new to WordPress. I have many sites that I plan to implement this plugin with – if I cannot get this working I will have to find a different one, so I really want to get this working.

I have installed and activated the plugin. I have chosen my settings appropriately. I will list all settings here:

Selector(s): a[rel=’m_PageScroll2id’]
Scroll animation speed: 1300
Auto-adjust animation speed: [checked]
Scroll animation easing: (idle)easeInQuint, (animating)easeInQuint
Scroll-to position: [checked]
Page layout: vertical
Offset: -100
Highlight selector(s): [blank]
Classes: [all default]
Force single highlight: [unchecked]
Keep highlight until next: [unchecked]
Highlight by next target: [unchecked]
Scroll to location hash, Enable: [checked]
Scroll to location hash, Enable for all targets (even for elements that are not handled by the plugin): [checked]
Scroll to location hash, Delay (milliseconds): 0
Disable plugin below: 0

My next step was to go to <b>Appearance > Menus</b> and I set each link’s <em?Link Relationship (XFN) to: m_PageScroll2id

I then included the selector rel=’m_PageScroll2id’ in my target anchors, for example:

<div id="products" rel='m_PageScroll2id'>

My cache is not the issue, I cannot figure out what I have done wrong (or what I have mised). PLEASE help me on this, I am used to coding websites without a CMS and I am sure/hopeful that this is simply a setting that I have missed.

Regards,
Danny
