How to roll pecan logs

I am having a hard time locating that recipe in our system.  If you are able to send us the recipe, we can most likely help to figure out what went wrong.  I do know that typically you cannot substitute 1 cup of granulated sugar directly for 1 cup of brown sugar -- they act differently in baking and can sometimes make a difference in the result.  However, if you can elaborate on what else is in the recipe/the method, we can be of more assistance.  Thanks!
