I tested this week in every possible way, but it didn't work, this appeared
my parameters

hello again, as far as the error message you're seeing ... without more information here I don't have enough to go on. If you could provide me with a screenshot of the console (pressing f8 when you get that error) and explain what you were doing when you got that error I might be able to assist.
And for your parameters, do you have a game switch #278 that is set to true while testing?
if you assign 'Use On/Off Switch' to true you must assign a game switch ID in the 'On/Off Switch ID' parameter and ensure that game switch is set to true. running an event or common event which uses 'Control Switches' and sets switch #278 to true.
is there a usable item in the database that is also id #278? typically users would have a few to a bunch of items listed in the 'Active Item IDs' parameter.
Example: 2 4 6 8 10
each ID separated with a space.
you also have 'Use Image Files' set to true. Do you have an image named '278.png' inside your pictures folder?
If you prefer to use icons, at least for testing, try setting that to false.
Also from my testing with the QMV master demo the keys q and e seem to be in use already by that plugin, are you looking to override those buttons? because my plugin after the latest patch would override the bindings set by QInput.
