Four numbered rooms

Click here to play on SudokuPad. (Unfortunately, I could not get SudokuPad to understand the constraints or do solution checking, so you will have to turn off the conflict checker in the SudokuPad settings, and there will be no indication on SudokuPad when the puzzle is completed. If anyone wants to impart some wisdom in that area, feel free.)
Classic: Standard 4×4 Sudoku rules apply in the main 4×4 grid. Fill every row, column, and 2×2 box with the digits 1–4 exactly once.
Renban Lines: Digits on each pink line form a set of consecutive digits, in any order, with no repeats.
Numbered Rooms: The four cells outside the grid are numbered rooms clues. Each corresponds to the row of the grid adjacent to it. A digit outside the grid must appear in the grid in the Nth position along its row (counting from the cell adjacent to the external clue), where N is the digit in the grid cell adjacent to that clue.
For example, if r2c4 = 3, then the external clue to the right of row 2 indicates that its digit appears in r2c2, since r2c2 is the third position when counting from r2c4. Similarly, if r4c1 = 2, then the external clue to the left of row 4 appears in r4c2, since that is the second position when counting from r4c1.
This is my first attempt at constructing a Sudoku puzzle, so I'm sure there will be kinks to work out; sorry in advance for any mistakes!
Solution code: The solution code is the second and third rows, with no spaces, and including the numbered room clues (so 11 digits in total).
