change access from from "unbound" to "bound"

I have a simple table in access database.
All I wan is to make one text box populated using drop down. For example.

My table
ID           County no                 County Name
1               1                                 area 1
2              2                                  area 2

My Form

County no                         "DROP DOWN"
Count Name                     "TEXT BOX 1"

I want text box to be filled out when I select the number in drop down.

Thank you much in advance for all your help.

first set the Column Count property of the combo box to 3

Column Count  3

in the afterUpdate Event of the combo box, place this code

me.[TEXT BOX 1]= me.[DROP DOWN].column(2)

.[TEXT BOX 1] is assumed to be the name of the text box and
[DROP DOWN] is assumed to be the name of the combo box

if those are not true, change them accordingly

Thank you for your response. I get the error with the pop up window when I make the suggested changes and run my form

"Microsoft Access cannot find the object "me."

Please help

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

There is no reason to store the country name but there are reasons for displaying both the country number and the name.  A simple, no code solution is to concatenate the country number and name in the query used as the combo's RowSource.

Select ID, [country no] & " - " & [country name] As CountryName From Your table
Order By [country no] & " - " & [country name];

Or, If you prefer country name first order then:
Select ID, [country name] & " - " & [country no] As CountryName From Your table
Order By [country name] & " - " & [country no];

I've attached a database with a sample that explains three methods of populating form fields from lookup values and when you should choose each technique.

I really appreciate details in he dataset you uploaded. I am really new to access though a very old VBA programmer in excel.

Using responses on this question I have setup the form in attached database. However the operator field still does not get populated. Further problem is there are repeated operators and if I use distinct query then I lost connection with County combo box..any suggestions please?

try this

Private Sub Combo_county_AfterUpdate()
Me.combo_operator = ""
Me.combo_operator.RowSource = "SELECT DISTINCT Permits.[Operator Name]" _
                            & " FROM Permits" _
                            & " WHERE(Permits.County) = '" & Me.Combo_county & "'"

Me.Txt_District = DLookup("District", "Permits", "County = '" & Me.Combo_county & "'")
End Sub
