dude i have a error the error will not let me play

 

I know that. The link I shared contains an example of how to properly do what you're trying to do. Check the example code closely and find the difference between your code and the example code. The error message you're getting is telling you exactly what's wrong.

 

it works but my code dose not work

Scroll down to properties to see what is available and then change your code accordingly.

If that still doesn't help you, either go to your local optician to get new glasses, or try something else than programming...

 

it worked

 

Well this hurt my brain
