Thanks for that, the mistake was in the menu buttons which were pointing at an .html page and not the .php one.

Next question, we sell vactaions and therefore each transaction is a different value, hence the need for your custom button. We also sell in 3 currencies, US Dollars, British Pounds and Euros, can I add the ability to select currency to the cutom buton? If so how do i do tis?

Many thanks
Michael
