I'd go with the Cadd2. Let's see if this helps
1st line below tells what fret. 2nd line tells which finger to use for that string. 6th string on the left.
8 7 0 5 8 x
3 2 . .1 4
Also take a look at http://www.guitarchords247.com/ where you can search for chords by name. Search for Cadd2 and if that doesn't sound right look for Csus2
Anot her site is http://www.all-guitar-chords.com
Maybe this pdf will come through too.
