I am trying to run a count calculation on a particular column that has duplicate values. For instance -1 , 1, 2, etc. If I create a calculated field and try using the running count function I get a count of all the values in the column instead of a repeating count for the different values or group of numbers. For example, if I have 10 (-1) values I would like the column to display a count from 1 to 10 for this particular value, and then have a new count for another value. Any suggestions on how to solve this problem??
