Can't know what the problem in my code pen

i am in the drum mechine project and i don’t know what the problem that is failing the final test

Welcome to the forums @ibrahim.sab2005.

When a test fails click the red button to see which test(s) are failing and text to help you correct the issue.
Be sure and read more than just the first line of the failing message. The ability to read and comprehend error messages is a skill you’ll need to acquire as a developer. Ask questions on what you don’t understand.

The full failing message says

When a .drum-pad is triggered, a string describing the associated audio clip is displayed as the inner text of the #display element (each string must be unique).
Each time a drum pad is triggered, a unique string should be displayed in the element with the id "display": expected false to be true
AssertionError: Each time a drum pad is triggered, a unique string should be displayed in the element with the id "display": expected false to be true

Do you understand what the test is looking for and why it is failing?

The test is looking to see the string in the #display element
In your code the string displays in the #info element.
