Don't you find it frustrating when someone starts a thread and requests help
with code that they obviously haven't checked?
"I've created this code" really gets up my nose when the comment lines( such as '// enter your words here')
show that it's just been copied from somewhere.
Download a reference manual and use it is my advice.
I'm not an IT professional, I'm a hobbyist, and I've learned all I know by research, and testing and more of the same!
