I am using this Canon digital point and shoot camera. When I press on the shutter, a couple of squares will appear on the screen. But how do I make the camera focus at the center of the frame?

What model of camera are you using?
For my Canon point and shoot DC, it gives me the choice of "evaluative", "center weighted average" and "spot".
In the menu, for AF settings, it gives me a choice of AiAF, Flexizone and Center.
Evaluative .. center weight .. average .. spot .. are NOT focus .. they are NOTHING to do in focus ..
Those are METERING .. mean .. calculate how much light is need .. and how much time is need for a pic ..
Make it simple .. like you are filling up a water tank .. the bigger and higher pressure hose to use .. the less time is needed .. that is the relationship between shutter speed ( time ) and ampture .. ( how big the space to allow LIGHT to get though .. )
