I don't have any parameters setup yet when I open a form it asks for
parameter. How can I get rid of this?
Access will prompt for a parameter if it sees something that it doesn't
recognize. For example, if you have a textbox with a Control Source of
[FullName] and there is no such field in the form's recordsource query, it
will ask for it.
Check the spelling (blanks are important, [FullName] and [Full Name] are
totally different fieldnames) and see if the parameter for which you are being
prompted is in fact in the form's Recordsource query.
