You likely want an exclusive range unless you want the space at the end.

	message.message[0...lastspace.to_i]

What if there's no space?  Then perhaps:

	message.message[0..(lastspace || -1).to_i]

Of course, that puts you back in the position of getting the full  
string rather than some truncated version with no more than your  
desired number of characters.
