Are you getting errors? Anything in the error_logs?

What was the code you tried when you set $message to be something first (like in my suggestion above)? (If you read that article, when I user wanted to use a phrase in the message, they had to set it beforehand like I am suggesting.)

okay, i did set the message inside a variable, not in the vbullein phrase manager and, where can i check the error_logs part? thank you :)

If you don't know where your error_logs are, you will have to ask your host. Usually they are in a /logs directory, but, like I said, just ask your host.

nothing there, but, i have found something interesting, if i execute the code in another hook, such as memberdisplay (hook for displaying the memeber profile) it works perfectly, so i suppose the problem is the hook itself

Yeah, that could be it. plugins can be picky about where you execute them. :)

okay i moved it to newpost_process and its working pefectly but i wonder if the newpost_complete thing its a bug or something like that

I don't think so. If you look at the code, you'll see $errors is processed right after newpost_process. newpost_complete is clear down the page after that, so using that hook_location wouldn't work for at least that.

okay then, i suppose next time im going to double and triple check the code around the hooks i plan to use, thanks a lot!
