Dim recvar
Dim addrvar
Dim grpvar
Dim rst As Recordset
Dim db As dao.Database
Dim findExisting
recVar = Forms!locspecificinfofrm.ActiveDataSubfrm!Record_ID.Value
grpVar = Forms!locspecificinfofrm.Location!Grp_ID.Value
findExisting = "SELECT [Addr_ID] FROM [Prov_Address_Bridge] WHERE
[Record_ID] = " & recVar & " AND [Grp_ID] = " & grpVar & " AND [Addr_Type] = 'Remit'"
Set rst = db.OpenRecordset(findExisting)
我收到以下错误:
运行时错误91:对象变量或未设置块变量
最初我认为这是对待我的最后一行:
set rst = nothing
但我用来测试查询的变量应该是某些,我只是不断收到此错误。奇怪的是,我在同一表单上的其他事件中使用了相同的代码片段,并且工作正常。

您需要设置db

Pelase,指定引发错误的行。我假设错误与代码一致:
Set rst = db.OpenRecordset(findExisting)
正如我所看到的,在您的代码中,您没有像这样设置db
的实例:
Set db = CurrentDb
或者,例如
Set db = wrkAcc.OpenDatabase("YourDatabase")
使用您的调试哟查看变量db是否不在Nothing
中。如果是,您必须在db
变量中设置dao.Database
的correcto实例。
