not sure if you expected a hyperlink to be produced by your "mark-up". just in case you're NOT sure, there are a few things missing.
the next character after your opening < should be the letter 'a' (w/o the sng-quotes - this HTML mark-up instruction is called an ANCHOR), then a space. everything else you have is correct, and should remain as you've typed it. however, one more thing is needed. after everything that you have typed, you need to "close" the anchor using the standard closing scheme employed by HTML instructions, viz. another < followed by a / and then an 'a' (once again w/o the sng-quotes), and finally a >..
here's your line of HTML
now, for instruction purposes, inorder to NOT have it appear as a hyperlink so that you can see my changes, i'm inserting extra spaces b/t certain characters. you should NOT put these characters in yours.
< a href="http://www.backpackinglight.com">test < / a >
remove the space which is after the < and b/f the 'a', but leave a space after the 'a' and before the 'h' of 'href'.
remove the spaces b/t the anchor's "closing" mark-up, viz. there are 3 spaces b/t the closing <, /, a, and > characters. they should NOT be there for it to work. leave any other spaces alone - they should be there. if you want a longer description than "test" for readers to see, it is 'ok' to have spaces in the description.
now here it is working
does this help?
