QuestionWhy doesn't this script work as expected? Pin

I'm trying to change the position of a background element on a web page in random increments each time any link on the page is clicked:

JavaScript
const backgroundElement = document.querySelector('.container');
const positionXY = [100, 25, 50, 75];
  
function randomX(positionXY) { 
    return positionXY[Math.floor(Math.random() * positionXY.length)]
  }  
function randomY(positionXY) { 
    return positionXY[Math.floor(Math.random() * positionXY.length)]
  }

document.querySelectorAll("a").forEach(a =>
  a.addEventListener("click", () => {
 
  backgroundElement.style.cssText = `background-position: ${randomX}% ${randomY}%;`
  alert("x position:" + randomX(positionXY));
  alert("y position:" + randomY(positionXY));
  }
  )
)


the alerts show me that the values are being generated correctly, but the background position does not change on click.

Any tips? Do I need to create a toggle-state?
