how to deal with it ?this is the help from stata.

invalid syntax;
__________ invalid;

invalid filename;
__________ invalid varname;
__________ invalid name;

All items in this list indicate invalid syntax. These errors are
often, but not always, due to typographical errors. Stata attempts
to provide you with as much information as it can. Review the
syntax diagram for the designated command.
In giving the message "invalid syntax", Stata is not very helpful.
Errors in specifying expressions often result in this message.
