can't create simple cart button in WordPress

I'm having great difficulty at creating a simple cart button in WordPress. I configured the code to add the product and send the user to the basket.

In a regular php page, outside of WordPress, the button code works:
http://www.lifeleap.org/222.php

With the same code, in my WordPress page, it does nothing:
http://www.lifeleap.org/shopping2/

I thought it might be a WordPress plugin or theme issue, so I created a fresh test install of WordPress, with no plugins, using the Twenty Fourteen theme. But the button on a page still does not work:
http://lifeleap.org/manage-test-blog/

Maybe I'm doing something wrong, but I am getting nowhere. I created a support ticket at aMember, and after a week, no luck.

The support from aMember told me the code should be uncommented. So I came up with this:

<!-- Button/Link for aMember Shopping Cart -->
<script type="text/javascript">
if (typeof cart == "undefined")
document.write("<script src='/manage/application/cart/views/public/js/cart.js'></script>");
</script>
<input type="button" onclick="cart.addBasketExternal(this,6); return false;" value="Enroll Now">
<!-- End Button/Link for aMember Shopping Cart -->

But that is pushing code...

Code:

... outside of script code. Anyone have any suggestions on how to create a simple cart button in WordPress that adds a product and sends user to the basket? Thank you for any help.

The fix was to put the script in the button in a js file, and call it the head using something like:

Code:

<script type="text/javascript" src="/js/myscript.js"></script>

I used the CSS & Javascript Toolbox to accomplish this.

Hopefully this will help someone if they ever have this issue.

Crap I want to do this, but I'm a total noob when it comes to CSS, what is CSS * Javascript Toolbox and how did you create a JS file?

CSS * Javascript Toolbox is a WordPress plugin. Purchase the pro version to support these guys - great plugin, especially with aMember.
