MOVI not trying

MOVI not retraining. I loaded the let there be light program and it worked perfectly . I wanted to change the let there be light to show me your pretty smile and it doesn’t retrain. now nothing works not even the let there be light. I didn’t change anything except the recognizer.say statement.
Any ideas

Do a line by line check between the original “let there be light” and your code.
If you are not getting any errors when the code compiles, most likely there is something in the code MOVI doesn’t like…
Also I have found that occasionally MOVI loses its mind, and needs to be rebooted.
Check your power source as well.
Hope that helps.
Uploading your code may be the next step so others can see your issue.
