```I'm new to Mathematica so this is a very basic question I think. but one
that has me hung up. I keep getting this error

Set::write: Tag List in {0,0,0,0,0,0,0,0}[1] is Protected. >>

my code looks like this.

*IN:*
For[i = 1, i < 6 , i++,
Print[
g = i;
k[g] = twoDcalc[e1, a1, nodes[[{edges[[g, 1]], edges[[g, 2]]}]]]
]]

OUT:
