Not sure, but...

if 1==1 then 'a' elsif 'a'=='a' then 'b' else 'c' end
=> "a"

if 1==2 then 'a' elsif 'a'=='b' then 'b' else 'c' end
=> "c"


With a cursory glance, I can only guess that your first condition is
always true.  Maybe somebody could pipe in about ERB if that's a
factor, because I'm not familiar with it.
