		///////////////////////////////
		PAGE BEHAVIOUR
		///////////////////////////////

		AJAX (should change page as user types or clicks)

		Campaign - Selected amount on dropdown should affect total price in base bar (prices above). Also affects basket contents

		Description - Should replace "Example Text Here" and link should open new frame test window to Web Address

		Web Address - Should replace http://www.example.com


		Checkboxes - Each should add $1.00 to total price in base bar and add to Extras

		0 Extras = Clear space, for example - 10,000 Visitors

		1 Extra = Non-plural, for example - 10,000 Visitors + 1 Extra

		2 to 6 Extras = Plural, for example - 10,000 Visitors + 2 Extras  or  10,000 Visitors + 6 Extras

		Bold Checkbox - Makes example text (advert description) bold / strong

		Highlight Checkbox - Changes advert background colour to #FFFBE9 and border colour to #F6C500
