How to make mobility buttons for mobile games work?

Hello, so I already know how to do this but I ran into a problem. I have 3 buttons, 2 of them are to move right and left and the last one is to jump but, when I try to jump while moving right or left it doesn't work, and the same thing the other way around when I try to move right or left while jumping it doesn't work. Please help me because I don't know how to solve this. Thank you.

When I said, "Hello, so I already know how to do this" I meant I know what the title of this post says.
