I've now came up with a solution which does what I was after, although it 
may not be most elegant solution.

The solution wasn't as hard to come up with as I first thought, and what 
I've done is used the onclick event for the checkbox - so, to call the 
ProcessCity.asp page as soon the user has ticked the checkbox, the 
following code is OK : 

<INPUT id=checkboxnewcastle type=checkbox name=checkboxnewcastle 
onclick="window.location.href('ProcessCity.asp?
city=NEWC&cityname=Newcastle-upon-Tyne')">Process All Cities In Region

Passing down the city code and name is a bit of a botch-job, as I couldn't 
quickly figure out how the ProcessCity.asp could detect which checkbox had 
actually been ticked (not that the checkboxes are held in a DIV and aren't 
specifically held in a FORM) - still, the solution works OK for now, 
although I'd really like to sort out identifying which checkbox was ticked.
