Rules confimation?

By TIEActor, in Star Wars: Armada

I got into a discussion over weather you can flip a card for crit OR use a weapons cards crit, I.e. overload pluse, vs. You can do all the above on a single attack.

Can someone confirm the right ruling AND show me where it states it. Didnt have luck in the rule book.

"The attacker can resolve only one critical effect per attack."

and

"The standard critical effect is "If the defender is dealt at least one damage card by this attack, deal the first damage card face up"'

page 4, under Critical Effects

So no, you can't do both
