Hi May
I use the recipe from the UK EDC book - it uses 400g flour, 1 sachet yeast, 50g olive oil, 200g water, 1 tsp salt and 1 tsp sugar. It comes out pretty much perfect every time, although sometimes I do have to add a little bit (couple of tsp) more of water or of flour.
I don't know which recipe you are using, but I am sure that trial and error will get you there. At the beginning I was so nervous about using the machine, I was inclined to believe I had to follow recipes exactly but now I have got a lot more gung ho and experiment a bit if I'm not getting the results I expect.
Good luck!
