The use of the has_tag function to display table at the end of post

I would like the following code to display to display at the end of a post if a specific tag is present for that post

[Code moderated as per the Forum Rules. Please use the pastebin]

I am using the SemiLogic Theme and put that code in a widget but it showed on all pages and posts. If were just all posts it would have been better but I am hoping that with the right use of the has_tag I will be able to call it for specific posts.

Thanks
