MySQL error with insert function in Nodejs (Javascript)

Im trying to use insert function and Im getting all the time an error :( Im trying to insert into user table a name of the user

My function:

 function insert(tableName, toField, value){
    connection.connect();
    var queryString = "insert into "
    +connection.escape(tableName)+" ("+connection.escape(toField)+")
    select " + connection.escape(value)+"";

    connection.query(queryString, function(err) {
        if (err) throw err;
    });     
}

and in the main code:

insert("user", "name", "Anna");

Everytime I get an error:

Uncaught exception: Error: ER_PARSE_ERROR: 
You have an error in your SQL syntax; check the manual 
that corresponds to your MySQL server version for the right syntax 
to use near ''user' ('name') select 'Anna'' at line 1
Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check
