我想做一个页面集合的通用会计科目目录树，结果没有目录树显示 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

Case "收款凭证_Table1"

Select Case e.Node.Level

Case 0

tr("贷方科目") = Vals(0)

Vals(1) = Nothing

Vals(2) = Nothing

Vals(3) = Nothing

Vals(4) = Nothing

tr("明细科目") = Nothing

e.Form.DropDownBox.Value = tr("贷方科目")

e.Form.DropDownBox.CloseDropdown()

Case 1

tr("贷方科目") = Vals(0)

Vals(2) = Nothing

Vals(3) = Nothing

Vals(4) = Nothing

tr("明细科目") = Vals(1).SubString(9,Vals(1).Length - 9)

e.Form.DropDownBox.Value = tr("贷方科目")

e.Form.DropDownBox.CloseDropdown()

Case 2

tr("贷方科目") = Vals(0)

Vals(3) = Nothing

Vals(4) = Nothing

tr("明细科目") = Vals(1).SubString(8,Vals(1).Length - 8) & "-" & Vals(2).SubString(13,Vals(2).Length - 13)

e.Form.DropDownBox.Value = tr("贷方科目")

e.Form.DropDownBox.CloseDropdown()

Case 3

tr("贷方科目") = Vals(0)

Vals(4) = Nothing

tr("明细科目") = Vals(1).SubString(8,Vals(1).Length - 8) & "-" & Vals(2).SubString(12,Vals(2).Length - 12) & "-" & Vals(3).SubString(17,Vals(3).Length - 17)

e.Form.DropDownBox.Value = tr("贷方科目")

e.Form.DropDownBox.CloseDropdown()

Case 4

tr("贷方科目") = Vals(0)

tr("明细科目") = Vals(1).SubString(8,Vals(1).Length - 8) & "-" & Vals(2).SubString(12,Vals(2).Length - 12) & "-" & Vals(3).SubString(16,Vals(3).Length - 16) & "-" & Vals(4).SubString(21,Vals(4).Length - 21)

e.Form.DropDownBox.Value = tr("贷方科目")

e.Form.DropDownBox.CloseDropdown()

End Select

凭证中只去到明细科目，红色代码不是把明细科目赋为空值？操作后不行我再加上绿色代码，还是不行，哪该怎么写？
