Joomla Virtuamart Calculation Help - PHP ?

I have created a directory website, that uses virtuemart, to allow users to purchase one of 2 membership schemes.

I have added a few other components, and somewhere along the line, the checkout cart calculation code must have been modified? I'm not sure thats why I need some help.

When purchasing a product all is fine right through to payment, but when i add a coupon/voucher code, the price shown in the cart is negative, though when you go through to pay the price is correct?

* It is a UK based site, so have selected 17.5% tax/Vat to be added to price.

* Am Using PayPal Business

* Have current version of Joomla & VM

* Have a permanent coupon set up at 50%

The site is www-dot-fitoutsupplychain-dot-co-dot-uk

The voucher code is startup50

Any Joomla/virtuemart experts out there, please help. My skills here are limited.

I have had some mod's made to other components and its very important that these are NOT altered, as other than this coupon problem it has taken ages to get all working correctly.

Skills: eCommerce, Joomla, PHP
