Can you paste the script code that caused this error please? And which version of MUSHclient are you using?

The documentation states the 2nd argument should be true or false, and defaults to true.



http://www.gammon.com.au/scripts/doc.php?function=EnableTrigger

This works for me:


EnableTrigger "mytrigger"

EnableTrigger ("mytrigger", true)

EnableTrigger ("mytrigger", false)

However this gives that error message:


EnableTrigger ("mytrigger", nil)

See the release notes for version 3.68 - it has been changed to allow nil to be explicitly provided, and still take the default:

thanks thanks
i found out the reason why
i had it as EnableTrigger("mytrigger", True)
caps on the word True...

thanks =)

Ah, ok. That would do it, as True would be undefined and thus nil. Oh well, you found a subtle bug in MUSHclient anyway, although you need to be careful, as using True and False will have unintended effects if you misspell them like that.
