Hope they help!

Here is the .vmf as promised. Go into the main room, to the left you will see 2 pipes, the neurotxinn is in the pipes. The countdown screen is on the wall at the back, hope this helps.

and when the player kills the neurotoxin, disable the trigger.

Isn't cancelpending a better option?
That allows it to be activated again in case you do need to add some more neurotoxin in case the test subject needs to hurry up a bit more?

Sometimes when I'm bored, I used the complicated methods of mapping.

Its been a while since i last mapped for Portal 2, looking at my .vmf again, i saw a Logic auto and a Point Client Command,in front of the big screen, copy these 2 entities into your map. Click on the vgui_neurotoxin_countdown entity, in the class info you will see Countdown time, change this to what ever you want. We will call your timer Countdown_Timer, to trigger the countdown, put in this output

onpressed Countdown_Timer enable, if you are using a button.

Thanks again, you help me a lot!
