There should be a space between a and href, ...L" and target, > and target, string and URL is your intended link and the target string is what you want highlighted
It is kind of curious that when I scroll over "here" in your test it does underline it as long as the mouse arrow is over it.
Also, how long is your URL that your are using? You might want to go to Tiny URL.com and use their service to shorten it to a usable length. It is free!
Sorry about that. ;-(
Let me try wording it out.
Left arrow,a,space,href,equals,quotes,yourURL,quotes,right arrow,space,your target string, space,left arrow,/,a,right arrow.
Forget about my commas and the period.
