If you are looking for help in the forum make a post about what it is you are trying to do within construct 3. Explain it, and step it out. Or, post your project file or at least pictures of your events and the problem so that people have some sort of reference. I understand that English may not be your first language, but you can't just ask why some mechanic that you have created isn't working without any information. There is no way people can help you.
