Your better of implementing a Ask for Discount Amount button where you can select the discount amount via a pop up. See: > [@\[New 4.1.37\] Ask Question Action](http://forum.sambapos.com/t/new-4-1-37-ask-question-action/1414): > > This feature was a missing piece in our automation system. Now you can ask questions to user and execute a command with selected command parameter. I’ll add more tutorials but I’ll show some brief examples. For example you can ask if he wants to print a bill. It executes Print Bill command by sending selected Button to Command Value parameter. You can define values for buttons. For example that can be asked when discount button clicked. When No discount butto… Scroll bars are generally not a good idea on touchscreens its just makes things a little more complicated. A good POS design should not have any scroll bars. I would suggest you do the above for your discount button problem. I would also suggest you reduce your button height for your categories and products so that you have no scroll bars. ---

Just put all the discount amounts in the Values field in the Automation Command Button so you only need one button. ---

Try just the numbers. ``` 5 10 15 20 50 ``` As you are passing **5% Discount** into the Action and that’s why it cannot calculate properly.
