I've just managed to lose my 1/2 pint button on my till, please could someone tell me how to put it right.

Please could you also tell me how you show a 1/2 pint with a product, ie 1/2 Carling.

Many thanks

to re-assign your half pint/second price key, turn key to pgm, 4 subtotal, 70, then press the key position where you want it, subtotal to finish,

hope this works
