I am redesigning my webite to sell one book online and have been working on the cost calculators for the four different postal regions (I have a slightly different page for each Zone). It's all looking good! BUT IT WON'T WORK.

I can't get it to link to my payment processing company .......... they suggested that I modify their examples, but that doesn't work and in any case are really not suitable for the sale of one book.

I feel I am only a spit away. If I can get the calculator variable recognised by their 'amount'. (I am a novice).

Thanks,

Mike
