Random Errors Appearing Up And Down The Code - ComputerCraft Forums (archive)

Posted 21 February 2012 - 09:02 PM

Currently I have this error

[string "disk/startup"]:308: '=' expected

when I try to run my program

The error keeps changing as I changing the code.
But its not changing logically :\
currently it says "os.sleep(4)" is at fault.
