What this means is that the compiler has interpreted the last line
of a do expression to be a generator (i.e. pat <- exp), which is
bad Haskell.
In your case, here is main:
> main=do userText<-getText
Occasionally, this may be caused by offside errors:
main = do foo <- bar
return foo
^ offside error, Haskell interprets this as not being
part of the do expression
