Region Event troubles

I'm using the region events plugin so that when a player steps into a certain area the event starts a cutscene. The event cues a common event. However I only want it to happen once, but because the event starts whenever you step into one of several areas every time the player steps onto another one of the region tiles the event starts up again. How can i fix it so triggering the event once stops it from occuring on all tiles?

I've barely started using RPG Maker so you'll have to excuse me if this isn't the fix you're looking for but I would imagine you could handle this with a switch and a conditional branch. Something similar to this?

You could call a map event instead and just use a switch or put the common event content in a conditional branch that's only valid when a switch is off.

Yeah using a conditional script seemed to fix it
