Okay these are the chords:

        D, G, D, Bminor, E, Asus, A

To play this song accurately your count is 1 2 and 3! (down down up down) There are two of this pattern (1 2 and 3, 1 2 and 3) per measure. The First D has two measures so you play the pattern 4 times(1 2 and 3; 1 2 and 3; 1 2 and 3; 1 2 and 3), and A and Asus are a measure divided, you play the pattern once for each chord (A 1 2 and 3; Asus ! 2 and 3). All the rest are the pattern is played twice.
It is pretty easy. The most diificult transition is from D to Bminor, you should focus on that!
