It was probably naughty of me to enter Java Script but I had tested it at home before posting here. To echo Joe's comments to anybody that may have an edit key, take care. It is necessary to understand the logic of what is there before any changes can be made. In this case, attempting to put the logic into English, the main function runs something like this:

function MakeABlueClickey()

if no location (URL) is given, a blue clicky can not be created so blank the copy area and quit.

As I got here, it hasn't quited so there is a location. I will now look to see if the user has given a name and if they haven't, I will assume that the clicky is to display showing the location (URL) as the visible part as well as the other part, set that and quit.

Ok, I'm still here so there must be both a location and a name supplied so create the thing as per the template Joe gave.

end of function.
