231,271 PointsI'm not sure what you mean, the code appears to be intended to change the color of the heading to red when you click on the button. It seems to accomplish this when tested.
When you say "It doesn't work", what result were you expecting?

2,028 PointsActually , when I clicked on button , the heading dint change the color. I made a mistake in the html code where I added the script before creating the button. Thats why it was not considering the button. I corrected it. It works. Thank you !!

231,271 PointsI overlooked that because I tested the code in a sandbox tool that includes the script without using the HTML to load it.
To facilitate the most accurate analyses, make a snapshot of your workspace and post the link to it here. That also eliminates the need to be sure pasted code is formatted.

7,558 PointsWhat do you want to happen? Looks like you are making the heading color change when you click the button. Are you expecting something else?
