hmmm if i recall correctly there is a trick to running ACTIONS on PSelements...

They are accessed differently depending on the version of Photoshop Elements, i think it was through the "How To/Recipe" palette. You used to need an "add-on" in earlier versions but i'm not sure if that's still the case. if you do need the add-on look here and go to the power tool section.

you can also read through this older article and see if it help.
