i didnt make url like jacek " index.php?page=new_conversation

i make a new_conversation.php in same folder (almanafi)
so when i click on send i have an error "The list of names you gave does not look valid."

but im shure that the username is right and its on the Database
it have ( - and . and _ )

and when i write a fake simple name fore EXAMPLE "facebook"
i have this error
--------------------------------

Can you post your code ? It sounds like you are not using the template system like I did but only removed half of it.

You're not including the init.inc.php file ? That is where the function is defined.
