desprits:
1) The data item "Temps" in the DBMS record set must have a data type of either "Text" (and the data contained in that item must be of the correct format (eg 10:25pm)) OR it must be of type Date/Time.
2) Given that the above is true, then the code as jel wrote will work correctly:
dim TotalTemps as date
TotalTemps = TotalTemps + TimeValue(adoTriTemps.Recordset!Temps)
