Tested it myself.
No issues found. I did it exactly as you requested:
The idea is that after 3 tries of the !help script a message should appear "Please try again after (timer amount) seconds" which involves a 30 second cooldown.
Unless by "tries" you meant that the command has triggered 3 times?
2nd question: Replace "!help" with "!help *"
* is an indication that any text can be used at this marker, be it before or after the word.
Also, I don't know what your purpose of the script truly is, just randomly saying "help (random user) with this/that." doesn't really make sense. If you want something different just let us know and we'll help you out with that as well.
