Time to sit down with your agent and ask some questions. Marketing is everything.
It is so important to understand what your agent is going to do or has done to expose your house to the market place. I have found accasionally the listing is there and due to some glitch in the system it does come up unless you have specfic information for the software to look for it. (adress, MLS number, parcel no) So talk it over with you agent and see what can be done to make it easy to find. He/she may not be aware the it isn't coming up.
You have hired that person to do this for you. Its what we get paid the "big bucks" for. :)
You shouldn't have to make it happen unless you are trying to market yourself.
