I know you don't want code, but here is the code:
Code: Select all
IF track = 1 NewIndex = index .
In the Transform > Compute function, you can replicate this command as well. Compute a new variable that is the same as "index". Then, at the bottom, look for the "If" slot and put in the condition "track = 1".
This only works if all of your counties have track #1. If there are exceptions, let us know.
