I have an event database that allows for sub-events and I would like the serial number of them to be a combination of the main serial number with a .0001 added to the end of each new record. So record one would be "SN of master record with ".0001 and the next sub-event would be "SN of master record with ".0002
Tried multiple versions of this
SerialIncrement ( GetAsText ( AV Projects::project_sn +.0001) ; .0001)
with no luck.
what am i doing wrong?
