Multiple checkbox

[colinod]

Hi im not sure if this is in the right area, but was wondering if anyone could help....

I am trying to make a list of checkboxes in a form and want to be able to check some of the boxes that relate to certain things.

For example, a list of all countries in the world and i want to select all european ones, click on the word europe and all countries that are are checked in the box.

example here, which i think uses javascript, but not sure how???

HTML file line 39 is the responsible function.
