checkout/invoice ..."total" costomise

I am changing site (1.38) back to 17.50 % Vat for U.K. Vat change .

At some stage in past I altered the "total " wording ,shown on invoice ,and page 2 of checkout to show "Total includes VAT at 15.00%) . However I cannot now find which files need changing .

Should have made a note at time ,slap on wrist :wacko:. Can anyone remind me ?Thanks

Thanks for advice . Tried using Developers Kit , entering by copy paste all and parts of wording but hasn't found file .Tried all the key or name boxes in Developers Kit .

Here is line from page source info when looking at relevant web page (This is when looking at page 2 of the checkout process , payment method , and specifically in the "your total " Box) :

O.K. solved it myself . It is the description in the " edit tax rates " option , which needed changing after changing the rate to 17.50 . :clap:Not sure why it did not show up in searches ?
