Hi there, I've been doing this tutorial: http://vrotvrot.com/xoom/tutorials/mineRide/mineride.html and I've got stuck on this bit where you use dupliframe button to multi-replicate the railway sleepers. I click on the button but nothing happens. I'm using v2.37a and the guy in the tutorial is using a different version but I cant work out what's wrong. Any suggestions? Thanks

Ive now worked out what I was doing wrong! Just incase anyone is suffering from the same problem, the solution is to press 'I' and create a Loc keyframe, well there's a mini tutorial for you, have a nice day.
