Tell us what’s happening:
The last repeating gradient should be fine but It keeps telling me to put building color 4 from 0% to 10%

Hi sorry, this is the CSS

.fb1c {
width: 100%;
height: 80%;
background: repeating-linear-gradient(
90deg,
var(–building-color4),
var(–building-color4) 10%,
transparent 10%,
transparent 15%
),repeating-linear-gradient(
var(–building-color4) 0,
var(–building-color4) 10%,
var(–window-color4) 10%,
var(–window-color4) 90%
)
}

Hint:
Setting gradient will work -

repeating-linear-gradient(
var(–building-color4) 0 10%,
)
