Image link to registry page fails to load page

I have two images on the home page and linked them to the registry page. When clicking on the image the page blinks and the home page remains. I right clicked on the images and clicked on open in new window and the address appears briefly in the address bar and then the "registry/" portion disappears and the page remains on the home page. The text link on the "create account" works. The following is the code.

This post is acting strange as you can see the tick marks above and nothing between them and the single tick I typed turns into is a double and the code disappears when I save the post. I've tried multiple times to enter the code and the problems repeats itself. The code I copied to place here is: a target="_blank" href="http://harleyfatboy.net/register/" between <brackets>.
