C# – subsonic 3.0.0.3 doesent seem to update the database

im using subsonic 3.0.0.3 activerecord and everything is fine and i get no error but when i update a database, it never seems to actually happen, can anyone spot anything i am missing here?! ta

code:

var myquote = createNewQuote();

var gross = 36.00;

myquote.totalcost = gross;  // set the new value in my model

UpdateModel(myquote); // update the model, something to do with dirty columns??

if(ModelState.IsValid) // check to make sure i have no errors in my model after changing it
            myquote.Update(); // command that is supposed to update the database????

i have put a break point on UpdateModel and looked into the model and the value is in the model as directed, i get no error and modelstate is valid too, but when i look into the database the totalcost has not actually been changed for that record????

i have also tried .Save() but this too does not seem to change anything ?????

am a little puzzled
