I have set this for the "Contrassegno" payment (the customer pays on the
reception of the goods), using an hidden variable and the shipping database:

in checkout.html:
[if value payment_method eq contrassegno]
<input type='hidden' name='contrassegno' value='1'>
[else]
<input type='hidden' name='contrassegno' value='0'>
[/else]
[/if]

and in shipping.asc:
pptt Poste Italiane IT 1 99999999 f 5.16 + [value
contrassegno]*1.54*@@TOTAL@@

this add 1.54*(total number of items) when contrassegno equals '1'

Bye, Scudi
