I recently created a drop down menu that outside users can use to specify criteria they wish to view within the database I have created. Once they have specified criteria and run the filter command they are brought to a form which lists the records they searched for. What I need to do is block the users from making changes to the records presented in the form once they get into it. Mistakes will result in changes to the master table which the form is based on. I can't have that. Is their any way I can block them from making changes?
