Hey, sorry I didn't respond for such a long time, had a lot of stuff to do and forgot this thread.
About the SimError:
Go to your trigger editor and you will see a hierarchy of folders. In all the folders there will be Triggers under them, like you know. However, just like the triggers are under the folders, the folders are under the custom map script section. It has the icon of a standard TFT map. Click on it and copy the SimError into it. Then you can just use the code I gave you before to call it anywhere in your triggers.
Now, concerning the map itself, I looked at the new version you uploaded:
I played it a couple of times with 4v4 (fullhouse) and here are the things that need a lot fixing:
General
1. Survivors get attacked while still at start, this confuses people a lot, since they are trying to figure everything out.
2. People 'steal' medkits, as in they take all the medkits so that their team mates do not have any.
3. SMG is completely inferior to the Shotgun, it is a lot less effective and people don't actually consider to use it because of this.
4. Don't let people pick difficulty. It ends up with the infected selecting high difficulty, and most people are noobs. Let host pick difficulty instead, or have only one grade of difficulty.
Balance
1. The survivors have it extremely hard to win the game, the infected hordes are huge and overrun them usually on 1/4 of the way. Make hordes smaller/less frequent.
2. Hunters should have evasion, so that they have a slight chance of doing a bit of damage even if they jump into a group.
3. Boomer's don't rain bile all over survivors when they die, only when they puke. Make it so boomers die from 1-2 shoots depending on weapon.
Suggestions:
1. Make a director AI like in the actual l4d. This AI is basically a script that decides when to spawn how many infected at what spots and what player they should attack. Instead of just spawning hordes all the time, spawn hordes according to how good/bad they perform.
If you spawn a big horde when survivors are at low health you are essentially ending the game, instead see how much hitpoints they have, healthkits, ammo and then create smaller hordes if they are wounded, and bigger hordes if they seem to have full hitpoints, etc. This helps create a balance, since players wont find the game too hard then, or too easy, since the waves will adjust to how good they are doing.
2. You are spawning to many pain pills, also make it so that smgs shoot infected in a line, and improve their damage slightly.
3. Give survivors some time, let no infected spawn until they reached a certain region, people hate being attacked at start straight away.
4. Gradually increase difficulty. Instead of letting people vote for difficulty, let infected have 50 hitpoints at start and then increase them up to 100-150 towards the end.
5. Revive is extremely bugged. When I was incapicated and after getting revived, the game lagged so hard, I wasn't able to move, and we all had to quit.
6. When all survivors die/reach the safe-house, let the survivors and infected swap teams, so that both sides get a shot, people were frustrated that they didn't get to play the other side.
7. Add molotovs and pipebombs, with friendly fire ofc, since these are extremely valuable to survivors. However, make them fairly rare so that they have to be used wisely.
its awesome...
that's not way to go...
