Error in building maker

When I try to run my script BuildSkyScraper, I get

bios:206: [string
"BuildSkyScraper"]:1: '<name>'
expected

BuildSkyScraper:

os.loadAPI.("Buildingparts")
print.("How tall?")
height = read()
Buildingparts.DoorLayer()
turtle.up()
Buildingparts.DoorLayer()
turtle.up()
Buildingparts.CeilingLayer()
Buildingparts.WallLayer()
for i=1, height do
turtle.up()
Buildingparts.WallLayer()
turtle.up()
Buildingparts.WallLayer()
turtle.up()
Buildingparts.CeilingLayer()
Buildingparts.WallLayer()
end
while not turtle.detectDown() do
turtle.down()
end

Buildingparts on pastebin:

Remove the dots infront of the brackets of the first two lines.
It shouldn't be…

os.loadAPI.("Buildingparts")
print.("How tall?")

… but rather…

os.loadAPI("Buildingparts")
print("How tall?")

Thanks! There were some minor other bugs but it works perfectly now.
