Still no success. >:(
Do you guys have any example of button counter at individual digits?
For example if I need to get 2135 number from buttons, I first go to first location by pressing a 'select' button and then pressing '+' button or '-' button to set digit 2.
Pressing the 'select' button again to move cursor to second location and taking use of '+' and '-' buttons.. same process for rest two locations.
At the end, 'Enter' button to save number 2135 in a variable.
Once I have your help, I will be able to adjust it in my main code.
Thanks again.
