Thanks.

I know I have a lot to learn.
I'm just beginning with rub= y and in this moments I miss a IDE where I can do everything step by step s= o I can see what went wrong.

Now refractor the if then 's and I hope= I can decline it to less then 5 if then's.
But that will be difficult. =

>=3B You're iterating over the wrong object. After you'= ve build the hash=2C you
>=3B have to iterate over this hash and not = the dices arrays again.
>=3B
>=3B The dices array contains only = the numbers. The h hash contains the
>=3B numbers and corresponding c= ounts.
>=3B
>=3B So it's not
>=3B
>=3B dice.each {|nu= mber=2C count| ...
>=3B
>=3B but
>=3B
>=3B h.each {|n= umber=2C count| ...
>=3B
>=3B Since there have been quite some e= rrors now=2C you should be more careful
>=3B with the code you write.= And you should get used to testing and
>=3B debugging code yourself.= The error message is telling you that the ">=3B"
>=3B operator has= been applied to nil (namely the "count" variable). So if
>=3B you di= dn't already know the problem=2C the first step would be to check
>= =3B why "count" is nil. You'd do this by outputting "dice"=2C since that's =
>=3B what you're iterating over. And then you'd probably realized tha= t it's
>=3B the completely wrong object.
