Thanks michael,

with the risk of sounding completely stupid, what program do i use to create and open the .JS file? Done a bit of googling and still unsure, there seemed to be a lot of reference to HTML and web pages but unsure how this translates to creating the .JS file. Do you just write the code in say word or is there a specific program you use to create it?

Cheers and sorry for the very noob question!
