reading tanks from openblocks

Hey there,

I was making a script for reading out a couple of tanks from openblocks 1.4

in a few posts I saw that you can read out the information from Openblocks tanks with

a = peripheral.wrap("openblocks_tank_1")
a.getTankInfo[1]

this is not working at all. In this version you have to use the following:

a = peripheral.wrap("openblocks_tank_1")
a.getTankInfo[1].contents.amount
a.getTankInfo[1]capacity
a.getTankInfo[1].contents.rawname

while I solved that little issue, I stumble across a crash in the OpenComputers computer when performing the following script:

local tankName = ""
local mon = peripheral.wrap("monitor_3")
local dir = "UNKNOWN"
local tank = {}
local maxT = 11
local row = 6
local tankAmount1 = peripheral.wrap("openblocks_tank_13")
local tankAmount2 = peripheral.wrap("openblocks_tank_12")
local amounts1 = tankAmount1.getTankInfo(dir)
local amounts2 = tankAmount2.getTankInfo(dir)
for t = 8,maxT do
tankName = "openblocks_tank_"..tostring(t)
tank[t] = peripheral.wrap(tankName)
end
while true do
amount = 0
capacity = 0

for t = maxT,8 do
  details = tank[t].getTankInfo(dir)
  if details[1].contents.amount then
   detaila = details[1].contents.amount
   detailc = details[1].capacity
   detailn = details[1].contents.rawname
   else
   mon.write("The Tanks can't register the data!!!")
  end
  amount = detaila + (detaila * 6)
  capacity = detailc + (detailc * 6)
  mon.clear()
  mon.setTextScale(1)
  mon.setCursorPos(1,1)
  mon.write(tostring(amount).." / "..tostring(capacity))
  while amounts1[1].contents.amount do
   amount1 = amounts2[1].contents.amount
   if amount1 <= 1000 then
	rs.setOutput("right",true)
	mon.setCursorPos(1,3)
	mon.write("Laat de blazes maar komen!")
	mon.setCursorPos(1,4)
	mon.write("XP Verzamelen AAN")
   end
  end
  while amounts2[1].contents.amount do
   amount2 = amounts2[1].contents.amount
   if amount2 >= 31000 then
	rs.setOutput("right",false)
	mon.setCursorPos(1,3)
	mon.write("Eindelijk....Rust!! :D/>/>")
	mon.setCursorPos(1,4)
	mon.write("XP Verzamelen UIT")
   end
  end
  sleep(1)
end
end

When I start the script It seems to work in the console. (No errors or such things.)
when I leave the console and go back to it (rightclick) I see that the computer is restarted.

What did I do wrong?

PS:
I added a screenshot of my setup as it is right now ;)/>
just to clarify my situation.

PPS:
the modems are setup like this: (from top to bottom)

[ openblocks_tank_12 ]
[ openblocks_tank_11 ]
[ openblocks_tank_10 ]
[ openblocks_tank_9 ]
[ openblocks_tank_8 ]
[ openblocks_tank_13 ]

I added the modem on the bottom later on ;)/>


I hope this is a little clear for you guys, Because I am getting a Headache from this puzzle :S

I'd say at a guess it is this line:

while amounts1[1].contents.amount do

You never reassign this, so gets stuck in an infinite loop, and so crashes because 'too long without yielding'.

Can you help me solve this issue? because maybe there is a better way to do this.

for t = maxT,8 do

"maxT" is 11, which is higher than 8; this loop is hence skipped entirely. Either change the order or set a step size of -1.
