counting and serializing occurences in a field

[robo3342]

i have a file with customer orders. so the same customer id will appear once for each order the customer has placed. i am trying to find some way to serialize each occurence. so for customer 500, i would be able to see that this is order #1, order #2, order #3, etc...

any ideas?
