You are using escape character here properly, you just misspelled the word “quoted”, it should be “quotes”. It’s probably why your code is not passing.
// running tests
Variable myStr should contain the string:
I am a "double quoted" string inside "double quotes".
// tests completed
// console output
myStr = " I am a “double quoted” string inside" double quotes"."
myStr = " I am a “double quoted” string inside" double quotes"."
