Haskell Indention error that wont go away

Error is on the line scoreH h b n:

parse error (possibly incorrect indentation or mismatched brackets)

When I indent it by one space more (not in line with the function definition) I get

parse error on input =.

 scoreH :: Hand->DomBoard->Int->(Bool,[(Dom,End)]

 scoreH h b n = 
   let
     lPlays = leftdrops h b
     rPlays = rightdrops h b
     lPoss = leftScoreH lPlays b n
     rPoss = rightScoreH rPlays b n
   in
     if (length(lPoss) /= 0 || length(rPoss) /= 0) then (True,(lPoss++rPoss)) else (False,[(_,_)])


 rightScoreH :: Hand->DomBoard->Int->[(Dom,End)]

 rightScoreH [] _ _ = []

 rightScoreH (h:t) b n
    |scoreDom h R b == n = (h,R):rightScoreH t b n
    |otherwise = rightScoreH t b n

 leftScoreH :: Hand->DomBoard->Int->[(Dom,End)]

 leftScoreH [] _ _ = []

 leftScoreH (h:t) b n
    |scoreDom h L b == n = (h,L):leftScoreH t b n
    |otherwise = leftScoreH t b n

Actually this problem has nothing to do with indentation at all, it's right there in the first line: the signature is missing a closing paren.

                      (Bool,[(Dom,End)]   )

This would have been more obvious if you had left a bit more space in there, like

scoreH :: Hand -> DomBoard -> Int -> (Bool, [(Dom, End)]
                                     ⚡                  ⚡ clearly not closing
