Order to get it to be universal you would use a switch and a common event to make it stop, In the common event you would want to use the Conditional branch and for the conditional branch you would want to use the timer command like so.
Example:
As soon as you make the timer appear you would want to turn on a switch which turns on the common event. The common event will stop the timer and display the message.
NOTE: Please look where you post next time.
