What did you do and what where you expecting? Most errormessage have an x to click on or are disappearing automatically.

i check already existing the name in beforeinsert event like
Eg: name, email id - fields
i check name is already existing validation in beforeInsert Event

 my code: $sql="select name from users where  company_id=1 and name ='{name}' ";
               sc_lookup(ds_sql, $sql);
               $msg = "Name is already exists";
               sc_error_message($msg);

Note : Name is already exists - error message showing. but x button is missing
