Help me in solving JS20D problem

My issue

this was my solution but it asks me “Did you remove ‘paragraph3’ using DOM?” I don’t understand what is wrong with the solution here.

My code

// Add the code below this line
var removeelement = document.getElementById('paragraph3');
document.getElementById('primary').removeChild(removeelement);

document.getElementById('paragraph1').hidden = true;

Learning course: Web development using JavaScript

Update: I changed removeelement to removepara and it works fine. Isn’t is just a variable? so shouldn’t it work even if I call it Banana?
