I have a node type with a number of term reference fields (i.e. size, color, shape) that I would like to use to create the title of the node.

So, for example, if I choose 1 foot, blue and round as my terms, I would like the node title to save as "1 foot blue round."

Is it possible to create the rule in such a way to set the title on the CURRENT node? How might I go about accomplishing it if it is possible? (I have had success using rules to set the title of a NEW node, but not the one I'm currently trying to save.)
