Yes but you didn't replace any of the information you deleted, like the code posted correctly, and your links, a schematic would be good as well.

Now, post your code as text, following the insructions here

That is why I gave you the link in my first reply. Please read it, it tells you how to use this forum. Being new is no excuse once someone has posted a link to what you need to do.
