Contracting Tensors: Multiply by g^αρgασ?

[pleasehelpmeno]

When contracting $R^{\sigma}_{ \mbox{ }\mu\nu\rho}$ to $R_{\mu\nu}$

Should one multiply by $g^{\alpha\rho}g_{\alpha\sigma}$? I often get confused with ordering of indices and such like

Why are you starting a third thread about this?

there was no real answer, ignore the ricci tensor i just mean in general then, I don't really understand the order in which the indices should go, if it even matters at all.

If you're not satisfied with the answers, you should say that in the same thread, not start a new one.
