Hi Colin! In such case my own preference is to have an additional field cUsername and to set filter to this field. By this way, your problem doesn't exist. >I have a form that is used for each users timesheet entries. The problem >that I have though is that each user has their own DBF. (i.e. >\DATA\THSHT\%user name%\TMSHT.DBF). Each user can only access their own >TMSHT.DBF. My question is this. I don't know which DBF needs to be opened >until the form is run so what is the best way to handle this in the DE of >the form?
