Dear roboticus,

Thank you for your helpful remarks. I have inserted code tags.

I'll try to clarify my task. I would like to separate the scored lengths into certain intervals. For example for the following data I would like to count the number of items that are less then 10, then the number of items between 10 and 20, 20 and 30, 30 and 40 and so on. Actually I need to build several distributions with different degree of detalisation. So the possible length of interval except 10 might be various 2, 6, 12 and and so on.

the actual output should be something like this: 

0-10  6 items
10-20 5 items
20-30 1 item
30-40 6 items

Thank you once more.
