Hi, I am relatively new to access and we have a current database in use. The problem is that people accendently change the dt in a field so I have been asked to creat a button which will lock it and another button which will unlock it so that the user can enter data into this field. I can go to form, design, creat a button but each button has a specific function which I have to select to it to perform that function. I cannot find one which say lock field and unlock field. Please please I am not stupid but will be grateful to anyone who can give me very basic steps on how to achieve this. Many thanks, Rajni
