ms access 2010 error 3825 on update query, regarding multi-value

app updates fields (text,Y/N,Memo,dates) in table in db(a). When completed, db(a) deletes a single record in db(b) and runs an update query to insert the data in db(a) to identical fields in db(b). The error occurs on the "docmd.RUNSQL" line below. The error is: error 3825;
"SELECT * cannot be used in an insert into query when the source or destination contains a multi-valued field". I have not created any multi-valued fields that I know of, and don't know how to determine if a field is defined as multi-valued.

vba code:
db.Execute "DELETE * FROM tblJobSpec", dbFailOnError

' Append new data for this Job
JobSpecFileName = DB_Template_Path & "CAC_Field_Surveyor_JobData_Template.accdb"
strSQL = "INSERT INTO tblJobSpec IN '" & JobSpecFileName & "' SELECT tblJobSpec.* FROM tblJobSpec;"

DoCmd.SetWarnings False
DoCmd.RunSQL strSQL
DoCmd.SetWarnings True
...etc,,,
