OK, where is my error in this line?

document.write('<a href="http://blackwhite.uk.com' + code + ' target="_blank">click here</a>');

It doesn't open a new window but stays in the same one - I know the error is a simple one, but I am blind to it today!

You forgot to end quote the link

document.write('<a href="http://blackwhite.uk.com' + code + '" target="_blank">click here</a>');

That was annoying me for ages and I just couldn't see it :thumbsup:
