急救！！！一个关于applyfilter的问题

咖啡2003

一个主窗体：frm_PriceList,子窗体：frm_PriceListLine

主窗体recordsource:tbl_PriceListHeader

子窗体recordsource:SELECT [tbl_PriceListLine].[pll_prlID], [tbl_PriceListLine].[pll_ItemID], [tbl_PriceListLine].[pll_LineNo], [tbl_PriceListLine].[pll_ItemPckg], [tbl_PriceListLine].[pll_Price], [itm_NameL1] & " - " & [itm_NameL2] AS itm_Name FROM tbl_Item INNER JOIN tbl_PriceListLine ON [tbl_Item].[itm_ItemID]=[tbl_PriceListLine].[pll_ItemID] ORDER BY [tbl_PriceListLine].[pll_LineNo];

子窗体中用一个文本框searchbox和一个按钮search来进行筛选，如下：

Private Sub Search_Click()

Dim strSQL As String

DoCmd.ApplyFilter , "itm_Name like '*" & Me.searchbox & "*'"

Me.Refresh

End Sub

在子窗体中筛选成功

但在主窗体中引用了子窗体后因为筛选直接使用主窗体recordsource，其中不存在itm_Name故提示出错要求输入itm_name相关值。如何解决？
