Always eject Disk

i tried to make little program that ejects a floppy as soon as its injected. But every time I am starting the program, I am getting the same error:'=' expected.

Code:

function Check()
local x= peripheral.isPresent("left")
local y= peripheral.getType("left")
If x==true and y=="drive" then disk.eject("left") end
end

Check()

I just don't get it !! What's wrong with this code ????

Split into new topic.

You have capitalized `if`. It needs to be lower case.

oh! thx!!

here is a better implementation:

local oldpull=os.pullEventRaw
function os.pullEventRaw(...)
local p={coroutine.yield(...)}
if p[1]=="disk" then
peripheral.call(p[2],"eject")
end
return unpack(p)
end
-- eject disks
os.pullEventRaw=oldpull
-- stop ejecting disks
