CubeCart

Hello, We have a CubeCart online store that sells only to UK customers and we only charge tax at 17.5% regardless of the order. We would like to pay a programmer to make these changes for us.... Therefore we would like to make it so that our store doesn't show tax as N/A but... shows the tax amount added at 17.5% - even when customers aren't logged in. Because at the moment it only adds the tax when customers log in. So at the moment it says: Subtotal: £24.50 Tax: n/a Basket Total: £24.50 We would like it to say: Subtotal: £24.50 Postage: £6.95 VAT 17.5%: £5.50 Basket Total: £36.95 I've looked around for any mods but can't seem to find one - would be grateful if any one could suggest a mod or we would like to pay a programmer to make this adjusment. Thanks Liam
