Really dumb question.....

[beamends <..hidden..>]

I'm trying to enter a payment for diesel. I just have a receipt, and
paid cash. I'd assumed that this would be a General Ledger entry using
the 7300 Motor Expenses account, but I can't see how to register the VAT
amount. I've probably totally missed the point, just for a change....

Any pointers appreciated.

Cheers
Richard
