You have to consider permutations as well and not just combinations.
This will increase the total number of ways.

this is done using integral solution method..

 

let x - no. of single steps

let y - no of double steps

 

x + 2y = 22

x = 22 - 2y

 

the possible values of y for x >= 0

y = 0,1,2,3,4,5,6,7,8,9,10,11

 

hence no.of integral solutions is 12
