Using subscripts in function-parameter names

I'm quite new to using Mathematica and I'll probably not use it much in
the future either, but right now I need to use it to calculate some
values for comparison. My problem is that I can't get seem to get a
function to work if the parameters have a subscript in the name. The
following demonstrates the problem (copied from the notebook-file):

(F[\(x\_1\) _, \(x\_2) _] := \[Sum]\+\(i  = 1\)\%2 x\_i;\)

Or put another way, a function F that takes two arguments
Subscript[x,1] and Subscript[x,2] and runs a summation over
Subscript[x,i] from i = 1 to 2.

Now, this is quite a contrived example and could easily be expanded by
hand, but what I need it for is much harder, with 8 parameters and
nested summations. As I understand perhaps Utilities`Notation` could be
used, but I don't understand how to use it. Could someone give a short
demonstration (if that is the solution), perhaps on the above example?
