You should probably not remove toDigitsRev, especially since it's normally a piece of the correct solution for sumDigits... Your current sumDigits is incorrect, try it on [100, 100].

Roelof,

It doesn't look like you ever call toDigitsRev. To keep the solution clearer, you should remove any unneeded definitions.
