Forum:Can i still normal summon after initial normal summon was nagated

i never really had to deal with this due to few cards that stopped summons but here recently more cards have come out that do this. I just assumed that u couldnt attempt another summon since the player still summoned eventhough it was negated, the ruling regarding "Great Shogen Shien"s effect. "an opponent can still activate one more spell/trap card if the first is negated" has made me question this.
