Please say me how...telescope

I want to make a telescope with the magnification of more than 20 times. I want to make it in my own home. I tried to make one using two convex lenses one og focal length 100cm(objective) and other of focal length 10cm(eye piece). So according to theoretical calculation it should magnify 10 timnes. But i found that it magnified only 2 times. I am depressed. Please someone suggest me how can i make a better telescope.

magnification is not an important thing in telescopes, you want resolving power.
