Collision showing error message

There is an error when the red ball hits the green ball. I know there are some naming issues which makes it difficult to find the issue. Any help would be appreciated

what about fixing these naming issues then to be able to find the problem?
also if you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.

Here is what you probably needed:
