BibTeX, biblatex and biber ⇒ AER packages

[depot]

I'm using the aer biblio style but not getting the right results. I'm calling the harvard and aer packages at the beginning. There seem to be 2 aer.sty files, though, and I think it's using the wrong one. Has anyone else had this problem before? Thanks!

If it helps at all, Bibliography styles should have the extension .bst, not .sty.

Right, I'm using \bibliographystyle{aer}, but before that, I'm calling the aer.sty package and that seems to be where the problem is.
