The correct URL was... drum roll please... number 3 - http://www.westnet.u-net.com/marx/online/marxonline.htm!! Hope you've bookmarked that site for future reference! So, what was wrong with the others? Fingers crossed you picked up on the following errors...

Number 1. http://www.westnet.u_net.com/marx/online/marxonline.htm

The original URL has a hypen between the "u" and the "n"... the above has an underscore! Ooops! This kinda thing does matter unfortunately!!

Number 2. http://www.westnet.u-net.com/marx/online/marxonline.html

The end of the above URL is ".html", whereas the correct address uses ".htm" - an important distinction and one that's easy to miss!

Number 3. http://www.westnet.u-net.com/marx/online/marxonline.htm

Nothing to say here... I spoilt the surprise earlier by telling you it was right! D'oh! At least its reappearance gives you another change to bookmark it! Enjoy!

Number 4. http://www.westnet.u-net.com/marx/online/marx online.htm

For some reason I had a mental block when I typed in this URL and a space appeared at the end of the address between the word "marx" and "online"... tsk!!

Number 5. http://www.westnet.u-net.com/Marx/online/marxonline.htm

So near and yet so far with this address. Remember, although domain names themselves may or may not be case sensitive... anything within that domain is... so here the word "Marx" with a capital "m" is what's causing the link to fall over.

Number 6. http:://www.westnet.u-net.com/marx/online/marxonline.htm

Whoops! Looks like I doubled up on one of the colons at the very start of this web address - it's enough to make the link fall over! This particular error will make your browser hunt for the address at YOUR website! Strange effect, huh?
