Hello! This is my first time posting here, so apologies if I accidentally break any rule--
I've been using rpg maker for a month now, but for the life of me I still can't get battle events to work properly. Ever. 
I would like a timer to start when the battle starts, and when it reaches 0 I'd like it to display a text message and give the player a game over. My problem is that I've noticed that, during battles, when a timer reaches 0 it returns to the map screen, and I don't know why- also, I can't get any conditional branch to work. 

The first event page ( with condition: turn no. 0) is basically just:

- start timer

- turn switch 0004: timer ON

While the second page (with condition switch 0004: timer is ON) is

- conditional branch: if timer 0 sec or less, then
stop timer
display text message
game over

(the timer is just 10 seconds long for testing purposes)

Yet none of what I placed in the second page actually happens and when the timer reaches 0, the battle simply ends. What did I do wrong? it's probably a really dumb mistake, but I'm still new at this... 

I attached a couple screenshots, if they can help
