Change comma on numeric keyboard to fullstop

[lemmings]

I have been working with SambaPos 2.99 for my American Diner.

I'am still in the configuration stages and are wondering if the comma in the numeric keypad (in the cash settlement screen) can be amended to a fullstop for input of decimal numbers such as £ 3.55, its going to be confusing as staff are going to miss the comma and input £ 355.

I have looked through the source code and unable to find the part of the code I would need to amend.

I found the numeric keypad in the ticket.module and have amended so a fullstop  is displayed
