You may not believe me but [userid] has a bug

hi
i use [userid] subsitiution in my code in the php auto action. i have more than 50000 user and recently some time i give wrong userid. i clear my code previous month and can not access but it return incorrect userid. is it possible check it?
also if is it possible, give me the path to file that define [userid] subsition.

[userid] doesn't exist. It's [user_id]. It isn't defined anywhere. It's pulled directly from their user object. It's impossible for it to be wrong.

For CB Auto Actions it will be from the user who triggered the auto action or the user object sent with the trigger all of which will depend on what the User parameter is set to and what data is contained in the trigger being used.

My guess is your code is wrong or you aren't understanding what variables the trigger you're using is sending. See the below for a list of triggers and their variables.
