/*
INSTRUCTIONS:
	- Paste this code in teh head of you page, or in an external .JS file (it's easier to manage JS this way and you should allways use it)

	- In your page, simply add  onclick="clng()" to the language selection button.
	- This script is made to work with 2 sets of files (eg: myfile.php and sp_myfile.php) whenever the function is called it will alternate between them.

Enjoy
