Learn CSS Variables by Building a City Skyline - Step 104

I have a problem with this code:
.fb5 {
width: 10%;
height: 33%;
background-color: var(–building-color2);
position: relative;
right: 10%;
background: repeating-linear-gradient(
90deg,
var(–building-color2) 0%,
var(–building-color2) 5%,
transparent 5%,
transparent 10%
);
}
It says this error:
You should give the repeating-linear-gradient a first color of --building-color2 from 0% to 5% .

The step 104:
On to the next building! It’s the green one in the foreground. Give it a repeating-linear-gradient with your building color from 0% to 5% , and transparent from 5% to 10% .

Please, help me!
