Error when trying to login using try...catch

Getting an error in my try..catch:

An expression of non-boolean type specified in a context where a condition is expected, near ','

         Try
            Dim connStr, cmdStr As String

            cmdStr = "SELECT [ids] FROM [sessionregister] WHERE [username=@User],[password=&Pass];"
            Using conn As New SqlConnection(connStr)
                Using cmd As New SqlCommand(cmdStr, conn)
                    conn.Open()
                    cmd.Parameters.AddWithValue("@User", User1)
                    cmd.Parameters.AddWithValue("@Pass", Pass1)

                    ElseIf ids <> "" Then
                        Session("ids") = ids
                    Else
                        Exit Sub
                    End If
                    conn.Close()
                    cmd.Dispose()
                    conn.Dispose()
                End Using
            End Using
        Catch ex As Exception
            TextBox5.Text = ex.Message
            Exit Sub
        End Try

User1 and Pass1 are defined earlier in the program.
