I suspect what's happening here is that you are presenting statements 
you have made up programmatically, and the values you are trying to 
insert include apostrophes that break the syntax of your SQL. However 
there isn't really enough evidence to decide unless you are prepared to 
show us the error traceback, possibly with a dump of the SQL statement 
you are actually trying to execute.

I apologize in advance if you are using parameterized queries (as you 
should to avoid SQL injection vulnerabilities among other major 
problems) but this message is typical of Access when it sees words it 
can't parse.
