Erasing 2 events at the same time.
 

Okay. I know this is a begginers thing or whatever. But I need to get it so once I complete one event, it erases that one and another one. If anybody knows how to do this, please help me out.

Use switches. At the end of an event make a switch turn on. Make a second page and the precondition be the switch u just turned on. On this second page do "Auto-start" and erase event...and ur done.
