First of all, JavaScript is case-sensitive, so if the instructions tell you to write I am a, then writing i am a is not the same.
Second, the instructions tell you that if you start and end a string with a double quote , then in order to actually have a double quote appear in the string, you must escape it by putting a backslash character ( \ ) right before it. The only backslash you are using in your string is after the word quotes", but you can not have the " before the \", because that signifies the end of the string.
