主题：求帮助，我想把组合框字符串当成表名用

下面错哪里了

Dim wfc As WinForm.ComboBox = e.Form.Controls("ComboBox1")
Dim cp As String
cp = wfc.Value
Dim jb As New SQLJoinTableBuilder("查询表1","'" & cp & "'")
jb.Connection　链接名　Name = "Sale"  
jb.AddTable("'" & cp & "'","产品ID","产品","产品ID")
jb.AddTable("'" & cp & "'", "客户ID","客户","客户ID")
jb.AddExp("产品","产品名称")
jb.AddCols("日期", "数量","单价")
jb.AddExp("金额","数量 * 单价")
jb.Filter="{客户}.客户ID='C01'"
jb.Build()
MainTable = Tables("查询表1")

先谢谢....
