Hi Ruslan I'm using OS 9.2 with RR 1.1.1. I have encrypted one fld in a BO that has 2 flds. put Valentina("DataBase_OPEN",theFile) into dbRef ----- get Valentina( "Field_SetEncryption", fldRef, "password" ) When I attempt to open the fld I get an error of 310 - wrong parameter. Can you tell me what I'm doing wrong with this? thanks Ron
