I just created that sample DB on my documents. the tables are not locked. in the main Db you can change any values in any fields. The problem is the date fields you can't enter any new value. the error will show up. so right now I cant tell what's going on. so i thought it might be access date setting or regional date setting etc.can you enter anything in the empname column?
can you change the value of an existng record?
wrong error message but just wondering if you have locked the table in some way or have the app in a read only folder
