how can i add up a quantity column in a datagridview and also a Total Price column with £ GBP currency, both are getting displayed as label.text
also how can I times the quantity column with the unit price column. this gives me the total price column figure
also where would i put the code because i have tried an example code but didn't work i want the item count and total price to change as the barcode is scanned and entered(so when the datagridview shows the result)
Thanks
Forgot to mention I'm a total beginner.
