sometimes when i click on the fast cash button they dont work.
i dont know the cause
but it happens rarely
any idea why?
Did you modify it at all from the default setup that I uploaded?
Also just to let you know I built in a constraint so it will not work if the amount of the Fast Cash button is less than the total amount. You can remove that if you wish but I prefer it so it will not allow accidental press or double use of same button.
Reason for the constraint is In my system if fast cash is pressed I expect it to pay for the transaction. I do not want my staff using it if its less than amount due. I would rather them use payment screen for this. Just remove the constraint if you do not want this.
Here is example of constraint you would remove this for each button:
yup it is the same and i also agree that the constraint for less than the paying amount should be there
let me observe once again then will update
