Help with Comparison with the Strict Equality Operator

I’ve passed all of the tests when I run this code except for the final test to use the strict equality operator. (===). This is basically the exact same task as the previous lesson with a slightly different operator, and this structure worked perfectly then. Am I missing something simple?

My code so far

// Setup
function testStrict(testStrict) {
  if (testStrict === 7) { 
    return "Equal";
  }
  return "Not Equal";
}

// Change this value to test
testStrict(7);
