You're not following the instructions:

  • Compare the variable $a to the string "5". Your script doesn't have a string of 5 anywhere. Your comparison is comparing the variable $a to the variable $isIdentical. $isIdentical will only hold the result.
  • Assign the results of the comparison to $isIdentical. You're assigning the number 5 to $isIdentical
