Hello Gambers ! Is anybody can tell me what is wrong about this ? IF Left$(Cdcol.text,2) <> "00" OR Left$(Cdcol.text,2) <> "11" THEN message.warning (" Verifier vos variables SVP","OK") This one give the same result(Don't work). IF not Left$(Cdcol.text,2) = "00" OR not Left$(Cdcol.text,2) = "11" THEN message.warning (" Verifier vos variables SVP","OK") °~Jack~°
