See table Uniq_Serials_Edited.

Note the fields "StartSerial" and "EndSerial",

Example: I have a form. If my users key in "00019" then I want to display the record where the "StartSerial" is "00019" and the "EndSerial" is "00208".

Similarly, user keys "00770" should display record where "StartSerial" is "00767" and "EndSerial" is "00777".

For sake of example, let's display field "Exterior Finish".

How do I do this "between" functionality?

on my ipad, so cannot look at your database, but here is how I would do it.

This assumes that you want to do this in the AfterUpdate event of a textbox called txt_Serial, and that these serial numbers are numeric, not strings.

Private Sub txt_Serial_AfterUpdate

    Dim strCriteria as string

    strCriteria = "[StartSerial] <= " & me.txt_Serial & " AND [EndSerial] > " & me.txt_Serial
    With me.recordsetclone
        .findfirst strcriteria
        if .nomatch then
            msgbox "no record found for this serial #"
        Else
            me.bookmark = .bookmark
        endif
    end with

End Sub

Open in new window

You may want to change the > to >= in the criteria string, but I got the impression you wanted to test [StartSerial] <= me.txt_Serial < [EndSerial].  You could also use:

strCriteria = me.txt_Serial & " BETWEEN [StartSerial] AND [EndSerial]"

but I prefer to use the explicit syntax, so I know exactly what I am getting.

Now, the challenge with this is what if you enter a serial # lower than the lowest # in the [StartSerial] field of your table, or greater than the greatest [EndSerial] in your your table.  What do you want to do then?

Try to compact and repair the database and upload. You may want to exclude objects not related to the current issue.
