so would something like i have on this page do what you need
http://www.goodbeachguide.co.uk/beach/wembury#waterquality
if you click on the ‘designated bathing waters’ link in the first para it should open a ‘lightbox’ with info about water quality. This is the same information across many of my beach pages. I could pull in other information if i wanted simply using a dynamic page and a url query string or just link to individual static pages.
So for example you’d set up a page about electrical current for the uk and you’d just make a link to the lightbox to open it from the london page and the oxford page. If you did it dynamically like above you could stick all this info in a database and have an output page to link to and have the url determine which one to return e.g infopage.php?country=england&type=electric
if i have the right idea of what you need?!
