Hey, @malek, no need to panic, all is well. 
There isn’t much I can do to help though, I more or less gave you any assistance I could- if you could let me know what you’ve tried, what is or is not working, I could help more.
Also, looking at your other posts, I understand you’re new to Unreal, and there are a lot of building blocks that you can use to put together the things you’re trying to do! I have a really in-depth tutorial aimed at beginners that really covers so many things, I think you’ll have a much deeper understanding and higher confidence if you do it!
