summation help

[jll6m]

I am trying to enter the following summation into Mathcad but having issues. Summation in the form of Sigma with m on top, n on bottom

m = infinity
n = 2,4,6...

Any suggestions?

If you post a sheet, it might be more helpful; try to save as Mathcad 11.

My only issue is notation. I'm trying to write n = 2,4,6... on bottom

You don't need to. Simply use 2n in the expression. However, you cannot use infinity as the upper limit for this numerical , but you can use something like 10^6.
