You must select the rows using the MARK function or CTRL-F1. Just highlighting the rows means nothing to Navision. The marked records can then be filtered using the MARKEDONLY function.
The normal means of calling and returning from a lookup form does not return filters. So, you must declare the lookup form as a form variable, and create code that returns the filter settings back to the calling routine.
