I always get this error: syntax error, unexpected keyword_end, expecting end-of-input and i don't know what to do.

def sum_nums(num) ;
long = num.to_s ;
sum = nil ;
n = 0 ;


While n < num.length ;
   sum = long[n] + sum ;
   n = n + 1 ;
end  

end

this is the code

You're missing the do in your while loop. You should also make "while" all lowercase.

while n < num.length do
   sum = long[n] + sum 
   n = n + 1 
end

also there is no need for the semi colon ( ; ) at the end of every line.

It is optional, but it makes your code look ugly IMO.

I agree.

Don't write Ruby like you write JavaScript - quite different!
