I set the data connection up and added the buttons, just as it was suggested in the link you provided. However, I have a couple more questions. Is it possible for someone who does not have this same data connection to view and update this form?
I would also like to be able to add a filter to this form, so that each technician can filter on his or her name and view only records pertinent to them. What would be the best way to accomplish that?
The person that should use the form, needs the same data connection as you, so you'll need to setup an ODBC connection on his/her computer too.
