Help with Error

I'm working on learning lua and I've got a path paving program that I made. All 700 lines of code are good expect for this one function I can't figure out what is wrong with it.

Here is the function:

function importFill()
--@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
--imports more fill blocks
--@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

 
  placeIChest()
  turtle.select(SpaceWithBlock)
  turtle.suckUp
 
  sleep(1)
  removeIChest()
end

line 308: '=' expected near 'sleep'
Any help on how to fix this would be great.

The error is on the line before it (line 306), where you have turtle.suckUp instead of turtle.suckUp(). Notice the parentheses. Looks like you just forgot them.
