Case sensitivity JS stuck

Tell us what’s happening:
Everything I did is correct but it always shows an error!
Any one can help figure where the problem is?

Your code so far


// Variable declarations
var stUdLyCapVaR;
var properCamelCase;
var titleCaseOver;

// Variable assignments
stUdLyCapVaR = 10;
properCamelCase = "A String";
titleCaseOver = 9000;

You did not follow all of the instructions:

Modify the existing declarations and assignments so their names use camelCase.

“stUdLyCapVaR” is not camel case.
