Scrollable portal shows first record- I want last

[alkhall]

I have 2 files(custinfo & rundate) linked by customer number, portal displays one record, the first in rundate, no matter how it(rundate) is sorted. I want portal to display last rundate, no the first. Any ideas.

Define the relationship to sort by rundate (descending). I'm presuming that rundate is a date field.
