Phone Table contains Extension, Type (Phone or Fax) and Availability fields.

I originally input data by Extension (primary key); however, on a related form, I want to filter the portal by Availability, sorting by Type. The portal works with the exception of the Sort Portal Records option. The records are still sorted by Extension. I tried sorting the underlying Phone table, but that did not affect the order of the portal.

Is there a condition that causes a portal to ignore the sort specifications?

There must be something else going on. The Sort order you specify in a portal will override the Sort specified in the relationship.

Thanks for the heads up. I created a brand new portal, same fields, etc. and it worked fine.
