For our purpose we are using the Unique ID code which is the part of the link after the =
See below for how the code looks
Note the / in the second code set.
Although the youtube unique ID code is significantly different for each video the process is the same. Remove everything before the = and the .com and add the bracketed youtube codes at the front and rear of the Youtube Unique ID as in the picture above.
(Do not try and play this video it has been removed, this is just an example)
