LIVE ACTION EVENT. (HELP)

Hello Guys, i wanted to ask you something.
I've been working on something i call it a live action event,
Let me explain;

-There are 2 characters a Monster and the hero.
-when the live event start you have 2 seconds to take an Option
-Dodge
or -Cast Magic

-if you not take 1 of those option's in the 2 seconds, the monster attacks the -hero, and then another hero comes and battles him in a real battle.

but my problem is the moment it attacks you, then i can't get the options go away, they keep on the screen and i HAVE to choose, oné of them, and he still uses it..

I hope you can help me with that or if you have a better way too do it, please let me know.

I hope you understand, my english is not soo good ;D ty
