To change Available to No you'll need an UPDATE query.

What's the name of the table with the Available field in it?

What's it's primary key? Is that primary key available on the form?
tang kiat seongAuthor Commented:
@Norie Reg_ID is the primary key.
what i want is when the car in booking the available change to not
NorieVBA ExpertCommented:
You would need an UPDATE query like this then,
command = "UPDATE [i]yourtablename[/i] SET Available = 0 WHERE Reg_ID = '" & txtRegID.Text & "';"

Open in new window

where Reg_ID is coming from the textbox txtRegID.

if in the return car also use same command?
NorieVBA ExpertCommented:
Not sure what you mean.

If you want to change Available to Yes when the car is returned you would use something like this.
command = "UPDATE [i]yourtablename[/i] SET Available = 1 WHERE Reg_ID = '" & txtRegID.Text & "';"

Open in new window
