Views code not accessing custom field

Hello -

I'm having a problem with custom fields and views code. I have a website with posts of news items. There is a page on the website with a posts list consisting of the title and an exerpt and a button that I would like to send the viewer to an external webpage to read more about the post.

For that button I'm using a custom field on the post page - the field is jw_url. Ive written code in Views to make a button that has as it's href the custom field (jw_url) from each post. I can not get it to work.

First - the short code keeps dissapearing from my page code. How do I make the short code persist? And how do I get the basic functionality of the link to work? Once I do that I can make the button created in Views look better.

Here are some screenshots and code:

Here is the code of the webpage with the news post feed:

If there's any help you could offer - I would appreciate it. I can't get the short code to stay and I cant get the code to access the blog post custom field.

Thanks for your help.
