I have saved a bill on trainingacademy database, Account called Val2, invoice number called gasbandppu
The ppu is 5.6 on the current bill, and 2.86 on the previous bill. I have put really high consumption in the current bill so that the difference would be over £100 (as that is what is in the validator) :
BUT IT DOESNT FAIL???????????

Gas unit rate has changed from the previous invoice: FAILED - the name of the Validator
'threshold=0.01' - the threshold set in the validator,, allowing 0.01p high or lower than the previous bill
'previous=2.50' - the figure in the Cost rate field (19854) in the previous bill
'MinimumQueryValue=10.00' - the minimum cost of the query, £10.00
'QueryValue=26.42916' - the difference (in £s) between charging the current units at 2.70 (current cost) and 2.50 (previous cost), ie 13214.58 x 0.20 (the difference between 2.50 and 2.70) = £26.42
'present=2.70' the figure in the Cost rate field (19854) in the present bill
