count specific values in a range

I need to count values in a range of values that score above 18. The values aren't consecutive (e.g. a, c, e, g). Once they have counted the values in this range that score above 18 I need it to return a value of 0 if count is greater than 2 and 1 if less than 2.

eg.
a c e g
2 19 3 24 There are 2 scores above 18 therefore the answer is 0.

And what is returned if the count is =2 ?

sorry 0 as well.

Will the values always be separated by one column or is there no pattern ?

For some yes but the rest there are two spaces. The exact order is below:

see attached for actual values. The columns with numbers are the ones in consideration.

Perhaps =IF(COUNTIF(A2:P2,">18")<2,1,0)

awesome that works - thanks heaps. I was trying to make it too complicated.
