I guess you wanted to write "resources.fixtures[fixtures_index+1]"
instead of "fixtures[fixtures_index+1]", and just "fixtures" instead
of "fixtures[fixtures_index]". Then also you may want to change "as
fixtures" to "as fixture", and then it will be less confusing.

#list is the same as a for-each loop, only with some extra variables
(like ..._index).
