Usually pawn would say, 'You have not defined the variable 'string' on line blah blah', but it doesn't, it ignores when I haven't defined a variable and when someone types a command where string is not defined (a format function to say the player has been jailed for %d seconds) the server crashes.

Well, I defined a global string variable for OnPlayerCommandText, so I shouldn't need to define it again for every command, but I do. The PAWN compiler ignores if I haven't defined string.
