I have a SP List 'SGC' where employees enter information via a form called frmIDEntry. Within frmIDEntry is a field 'AssignedTo' that is a LookUp from another SP List 'EmployeeShort' - fieldname = 'FullName'. When employees enter records, I want AssignedTo to default to a specific LookUp value which is "---" (others will change this value later...but I'm just looking for a default).
I have tired each of the following in the default section but continue to receive errors...
If(frmIDEntry.Mode=FormMode.New,LookUp(Choices(EmployeeShort.FullName),Value="---",Parent.Default)
or
LookUp(Choices(EmployeeShort.FullName),Value="---")

Any suggestions?
