Hi again Mark,
i have tested your sample it runs well and

and i have modified it small

** old CREATE CURSOR crsRunTimes (MachineName C(2), nRunTime I)
CREATE CURSOR crsRunTimes (tarih d(8),MachineName C(2), nRunTime I

** old INSERT INTO crsRunTimes VALUES (lcMachine, crsMachineRuns.LogDate - ldStart)
INSERT INTO crsRunTimes VALUES (ldstart,lcMachine, crsMachineRuns.LogDate - ldStart)

CrsRuntimes cursor browse window looks like

Tarih machineName Nruntime
02/09/2002 M1 32
03/09/2002 M1 123456
..

Thank you very much i think thats enough for me and i think that was great solutions for me
Congratulations
