Not all devices support the ability to move apps to the SD.  I see from your other posts that you have an Alcatel OneTouch Pixi, which is an entry-level phone that I assume comes with very little internal storage.  These kinds of phones are very basic, and are mostly good for making calls, texting people, and browsing the web.  You can install a few apps, but the low storage prevents the user from installing a lot of apps.  If my tips at the beginning of this thread didn't help, then I'm afraid all I can suggest is to upgrade to a phone with more storage memory, or resign yourself to the fact that your current phone isn't capable of acting like a flagship or midrange device.  Sorry!
