predict.gam problem

Greetings

I am facing difficulties in prediction on using Trevor Hasties GAM package. 

How can one interpret the response from predict.gam?

Documentation on the type-parameter:
  The default (link) produces predictions on the scale of the additive 
  predictors, ... 

  If "response" is selected, the predictions are on the scale of the
  response, and are monotone trans-formations of the additive predictors,
  using the inverse link function.

Does "on the scale of the response" ammount to residals? 

All I want to do is get the predicted response from running my GAM model
on new data. The results given are way off, but I am not able to dechipher 
the documentation, nor use any scale information.


Any help will be highly appreciated.


All the best
