Lookup doesn't work in portal

[Peter Lars Jensen]

A customer database solution based on a relation between a Company db and a Contact person db. In the main layout of the Company db I have a portal row showing related contact persons of the company.

This is the way it should work: Make a new record in the Company db, fill it out, select the first portal row, type in firstname, tab will bring in information from the Company db from a lookup.

This doesn't work proberly :-(

The information from the Company db should be copied to the Contact person via the lookup when tabing in a new contact person, but only if a) I delete the just typed in entry in the portal and try again, or : if I type in a new entry below another portal row already existing.

Any help would be greatly appreciated!
