ComputerCraft loops

Hi there,

I've seen that you can now use ComputerCraft computers to read the charge from a BatBox, an MFE or an MFSU. Very happy to see this, I immediately made a program that shows the charge level of my MFSU with coloured lamps. This program is supposed to read the charge level and update every 2 seconds. This is the program:

Code:

mfsu = peripheral.wrap('right')
 
while true do
  charge = mfsu.getChargeLevel()
 
  if charge == 0.00 then
    rs.setBundledOutput('left', 0)
  elseif (charge <= 0.33) and (charge > 0.00) then
    rs.setBundledOutput('left', colours.red)
  elseif (charge > 0.33) and (charge <= 0.66) then
    rs.setBundledOutput('left', colours.red+colours.yellow)
  elseif (charge > 0.66) and (charge <= 0.90) then
    rs.setBundledOutput('left', colours.red+colours.yellow+colours.lime)
  elseif (charge > 0.90) and (charge <= 1.00) then
    rs.setBundledOutput('left', colours.red+colours.yellow+colours.lime+colours.green)
  end
 
  sleep(2)
end

The colours in the bundled output are same colours as the colours of the lamps that receive the redstone signals.

Anyway, the problem with this program is that the program only loops once, even though it is supposed to loop infinitely. If I try to use a for loop or a repeat loop, the same thing happens, it only loops once.

Does this happen because there is something wrong with my code, or are loops disabled on the server?

TL;DR: While, for and repeat loops do not work in my code, are loops disabled on ComputerCraft computers?
