从其他表访问Vba序列号

Question

我有两个表，ID表和Mastertable。在身份证表中，我有一个开始数字的级别和活动，让我们说1000.在Mastertable中，我拥有许多与同一活动和级别相关的图形。我必须从ID表值1000开始为它们编号，并将它增加1.完成后，mastertable的最大值必须重新插入ID表。

而且，如果有水平和活性，该ID已被拾起仰视的水平和活性都，如果没有级别届时提及它只能查找活动。

我尝试了很多，但不能成功。

我使用了下面的代码，但它只查找Activity而不查找级别。它也不会返回到id表并更新主表中的最大ID。

Option Compare Database 
Option Explicit 

Public Function SequenceNew() 
Dim strSQL As String 
Dim db As Database 
Dim rs As DAO.Recordset 
Dim a, initNo As Integer 
Dim b As Integer 


strSQL = "SELECT * FROM MasterTable ORDER BY LevelID" 
'Set db = CurrentDb 
Set rs = CurrentDb.OpenRecordset(strSQL) 
If rs.RecordCount > 0 Then 
rs.MoveFirst 
Do While Not rs.EOF 

rs.Edit 
If rs![DrawingTypeName] = "Concrete" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then 
a = a + 1 
rs!Sequence = DLookup("CONCRETE", "Qry_ID_Selected") + a 

ElseIf rs![DrawingTypeName] = "Reinforcement" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then 
b = b + 1 
rs!Sequence = DLookup("REINFORCEMENT", "Qry_ID_Selected") + b 

ElseIf rs![DrawingTypeName] = "Steel structural works" And rs![ProjectName] = Forms!frm_Publish!CboProject And rs!IDGiven = "Not Given" Then 

End If 
rs.Update 
rs.MoveNext 
Loop 
rs.Close 
Set db = Nothing 
Else 
MsgBox " No records Found" 
rs.Close 
Set db = Nothing 
End If 

End Function 

应该有一些其他更好的方法来做到这一点。 MasterTable ID Table

该问题是由我可以解决的新代码。
