How can i use more than one event sheet?

Hi. I'm making a game and the first event sheet is getting a bit large...so i'd like to add more stuff in another event sheet...but how can i set an "active" event sheet? I've added some events but they're not firing up as it would seem that the event sheet 1 is still "active"...is there a way to change active event sheets?

I'm using the free edition of construct 2 btw

You have to Include your new event sheet on the first one. Select your first event sheet, go to the Event tab at the top tool bar, and press Add include. Pick your new one.
