Computercraft expecting an '=' in line 37

Hi,

I'm trying to code an automatic cooling system for my reactor, when you type 'on' in the terminal redstone will turn on the system or off will do the opposite.

I wanted the terminal to always display a main page, welcoming them to the terminal and therefore the code is quite large as whenever a command is entered such as on, I had the terminal write Turning on… the script sleeps for a few seconds then the terminal will clear and re-write the welcome page.

Can you please try however to debug what's wrong. The error is happening on line 37, where I set the cursor pos.

local monitor = peripheral.wrap("top")
while true do
monitor.clear()
monitor.setCursorPos(8,4)
monitor.write("Cooling System:")
monitor.setCursorPos(13,8)
monitor.write("OFF")

term.setCursorPos(7,3)
term.write("===================================")

term.write("===================================")
term.setCursorPos(1,9)
term.write("To control the cooling system, please type either")

term.setCursorPos(1,11)
term.write("cooling system see monitor above. When turning on")

Take a look here, it should help you out. :)/>

You have an extra " on that line
term.setCursorPos("1,17)

Your error is actually on line 36 term.clear should be term.clear() as well as line 64 and the error that anavrins stated is on line 83 Also, delete one of your ends

To add to what Dragon said, this line:

else if input == "off" then

should be

elseif input == "off" then

goto here to get the code I made for this :)/> it even uses buttons :D/>
