Question

I have query table copyQuery which has Soil Condition has one of the columns, I need to make combo box soil_cond in another form to have default value of Soil Condition from copyQuery.

Combo box soil_cond has three values not a query.

So I tried this and entered the following to default value of the combo box soil_cond but it is not working.

=DLookUp("[Soil Condition]","copyQuery","soil_cond = [Soil Condition]")

Row Source is "Backfill";"Insitu"
Control Source is Soil Condition

copyQuery is table from this code:

Private Sub copy_record_Click()
  Dim query As String

  Set dbLib = CurrentDb()

Try the following:

=DLookUp("[Soil Condition]","copyQuery","soil_cond ='" & [Soil Condition] & "'")
