I'm new to portals. Just getting started.

I have a table with three fields:

number field: PRIORITY

text field: DESCRIPTION

container field: IMAGE

On a separate layout I have a portal that shows the container fields, a dozen records at a time.

I would like to constrain the portal to only showing images of a FOUND set.

For example, if I perform a search for records that have priority equal to "2", then just those images (but ALL those images)

would show up in the portal.

Is there any way to filter the portal so that it only shows these records?

There is a relatively old, very elegant and powerful and easy way that requires one custom function. The sample explanatory files containing everything you need to implement displaying your found set in your own portal can be obtained here.
