It doesn't look like you've written any code yet.

If you are completely stuck and don't know where to begin, you might want to rewatch the last video: Working with Strings and Finding Help.

All the examples given for the toLowerCase method would apply equally well to toUpperCase.

You haven't made any edits to the code. Remember, to change the content of a string variable to upper case, you have to call the toUpperCase() method on the variable. Check out the MDN documentation on the toUpperCase() method for more information.

var agency = "nasa";
var spaceAgency = agency.toUpperCase(); // returns the string "NASA" and assigns to spaceAgency variable.
