Hi I''m sure I''ve read somewhere that you can count up in ''jumps'' using ruby? I''ve got two times and I want to basically go up in 15 minute jumps without using the whole for loop thing. Any helpful ideas? All my ruby books are in storage and I can''t find anything on google ...but then I''m not sure what I''m looking for! Thanks in advance. Code: <%- (@info[0][1].. @info[0][2]).???? do %> Darren
You probably talk about the step function (http://www.ruby-doc.org/ core/classes/Numeric.src/M000189.html). Always look first the Ruby API. Regards. Franco Catena.

Yeah thanks! Just after I posted it I remembered my pascal (or similar) days and step came into mind ... (@info[0][1].. @info[0][2]).step(15.minutes) do |i| Seemed to do the trick nicely!
