Help cannot take screenshot on mytouch 4g


I am trying to take a screenshot of my phone and seem unable to do so. I have tried pressing and holding the home (looks like a house, on the touch screen) and the power button at the same time.

All I get is either the power off options, screen goes to home, the screen goes to recently used apps, or some combination of these.

I do not seem to have a folder for screenshots under the camera

I am using android 2.3.6

Phone is less than a week old
