controlling records displayed in a portal
I have a form with a portal that displays records from a related table.
In that related table there is a field is either has the value "true" in it, or its empty.
I would like to have a check box that enables me to either show or hide the records with "true" in them in this portal.
Could anyone help me out to figure out how this works? I simply need to be able to choose to hide or show those records.
