Thank you very much, it worked now.

What is the difference between declaring "int[3] a = [1,2,3];" 
and declaring "int[] a = [1,2,3];"? Is the first an array and the 
second a range?

I always thought that leaving the square brackets empty would 
create an array of flexible size, it never occurred to me that it 
was creating something else.
