Workflow Activation

This is probably a dumb question...well it is...I have yet to take the classes for EPDM. We are due to have a new server installed in the coming weeks, and will be  having someone come down for everything EPDM. Aside from that I'm trying to get my feet wet in the mean time. Currently I'm dabbling in Workflows, trying to figure out what we need/want and how to accomplish it. There was a few workflows already, and i decided to make my own. (we are piggybacking on a different divsions testvault right now). I made my own small simple workflow. But when i check in parts it always references a different older workflow. How can I get it to reference my new workflow?

I went in to all workflows and under properties deleted any conditions as i thought thats what was doing it. But it still references the old workflow.

I tried checking the admin guide...but if the answer is in there i didnt see it.  How can i begin to use a new test workflow? Definetly confused. They don't make EPDM user friendly thats for sure.
