Learn CSS Variables by Building a City Skyline - Step 60

[cristinimatteo]

Hi,
that’s my code so far
background:repeating-linear-gradient(
90deg,
var(–building-color3),
var(–building-color3) 7.5%,
var(–window-color3) 15%
);
}

but i don’t understand why the system keep telling me :

You should use --window-color3 at 15% for the third color.
