ok understand.
actually we have a request from a old man running a restaurant and we are helping him out to do it… he requested for a currency calculator something like this http://www.onlineconversion.com/moneycounter.htm
so im thinking if there can be a button on the POS screen and once selected the currency calculator will display for entry. and also to print out the entry
i know the above is hard to achieve and so im thinking of a message box that can link to http://www.onlineconversion.com/moneycounter.htm
