When following the tutorial under (4.41. Item Based Discount on Order Screen) Step—>(1-Disc Remove Numberpad)

I follow the steps but the discount does not work.
I assume it is becuase i am missing this part.

No need to find. You can write it maunally. Then you will create a rule and you will use same automation commmand name in this rule.

Thanks I found my mistake , I had {SETTING:NUMBERPAD}
as {SEETING:NUMBERPAD} .Now it works.
Thanks for the quick response.
