That’s the original problem, Sneak is not in your project, for that reason is need create one Input with the name “Sneak”.
The same will happen with Horizontal2, Vertical2, Reload, and Holster.
To create buttons, go to “Edit->Input” and increase the number of entries, after that, select one of them and change its name, for example Sneak, and change it Positive entrie to any key, for example “q”.
