What it appears to me, is the error is telling you to look at building 1 code more carefully. Did you type all characters correctly? It looks like there may be a difference in building 1 and the others.

I typed the first building with 2 dashes but for some reason on my post only 1 shows up. Any idea of what would be wrong besides that?

:root {
–building-color1: #000;
–building-color2: #000;
–building-color3: #000;
–building-color4: #000;
}
