Ive been wanting to play this certain version of "orange" on the piano, but all it gives me are the chord progressions and i dont know much about them!

Heres the link to the video, the chord progressions are in the description:

Piano chord fingering sites (http://www.google.com/#hl=en&safe=off&q=piano+chord+finder&aq=f&aqi=g7g-c1g2&aql=&oq=&gs_rfai=&fp=214be73b764a3df5)

This is a good one (http://keychord.com/)

This one's nice too (http://www.gootar.com/piano/)

It looks like these sites will just show you root positions. Obviously, you just make the 3rd, 5th, 7th, etc the bottom note while shifting the former lower notes up an octave if you want to make an inversion (I'm sure you know that already, I hope).

Does your piano have styles? A button that says "Accompaniment"? You can have the keyboard accompany you by playing chords with your left hand and the melody in your right. It should tell you what chord you're playing, which is helpful. So many 7th chords... but if you're just starting to learn, then ignore the 7ths and practice triads first to get the hang of it. It's still correct even if you dont play the 7ths.

Solaphar, I don't think he knows what an inversion is because he doesn't know anything about the technical stuff behind a chord (a lot of beginners see it as a block of notes and that's it). http://Musictheory.net is my #1 source for music theory for beginners and novices. I recommend that.
