“学费”附近的语法不正确

Question

openconnection()
    Dim cmd As SqlCommand
    If Val(TextBox1.Text) - Val(TextBox17.Text) > 0 Then
            cmd = New SqlCommand
            cmd.Connection = conn
        Query = "UPDATE Students" &
            "set tuition = '" & Val(TextBox1.Text) - Val(TextBox17.Text) & "'" &
            "where id = '" & Form9.TextBox10.Text & "'"
            cmd.CommandText = Query
            cmd.ExecuteNonQuery()
            MsgBox("Sucessfully paid account")
            Form1.Show()
            Me.Close()
        End If

有人可以帮我找到问题吗？它说“学费”附近的语法错误。如果有人能够查明问题，请高度赞赏。感谢
