[JavaScript] JS div to remain visible

[Alan Easton]

Hi Laurent,

Thanks for the help yesterday.

I tried what you suggested and I now have 2 pages, just for testing, so I 
can navigate between the 2 and capture which layer was open.

But I am getting an error as I navigate from one to the other. Would you 
mind having a look to see where I have gone wrong. I am navigating from 
HTMLPage1.htm to HTMLPage12.htm.

It is when you launch the first page, HTMLPage1, because the onload event is 
firing, but there is initially no 'divClicked' being passed, it is nothing 
and therefore the error is coming up.

Any help would be appreciated.

Thanks,

Alan...
