Crashing stuff with chat commands

In here they say, that it is not possible to crash the game with adding gold.

However, some things can.
I made an ally trigger that:
Activates if someone says -ally
Check what's after it and then allies, shares vision, shares xp, shares friendly spell targeting. (Not all is needed, but that's how i did)
So if i say -ally 2 then it allies player 2 Blue.
It was only supposed to accept numbers, but i found no way for it to check if something is a number.

I used this trigger in my map until someone said -ally red
The game crashed.
If any non-numerics result in zeros, then i guess it tried to find player 0.

substring 7 has to be a number between 1 and 12
1_2_3_4_5_6_7
-_a_l__l_y___2

if false, then else function: print message "syntax error" or something

i triggered an example for you

example

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) types a chat message containing (Substring(-kill, 1, 5)) as A substring
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Substring((Entered chat string), 7, (Length of (Entered chat string)))) Equal to (String(1))
      • Then - Actions
        • Unit - Kill Paladin 0002 <gen>
      • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Substring((Entered chat string), 7, (Length of (Entered chat string)))) Equal to (String(2))
          • Then - Actions
            • Unit - Kill Archmage 0003 <gen>
          • Else - Actions
            • Game - Display to (All players) the text: ((Substring((Entered chat string), 7, (Length of (Entered chat string)))) + not found :D lol)

Thank you. It made my trigger 12 times shorter lol.
What do you think is the best way for making a chat command for spawning stuff?
Lets say i want to have over a hundred units in choice.

The Convert index to player function crashes when the index is out of bounds (in GUI 1 to 16). If you try to convert a non-numeric string to integer, it will return 0.

Or wait, that way i would still need to make 12 different options, which makes it very long and clumsy. But i think i know what to do now. Yep, it works. I made it use integer A.
For each integer A from 1 to 12 etc
Then it checks if the chat string is the same as integer A and if it is then it works. Else it tells an error.
