Evaluation Control

I am writing a function which involves manipulation of lists, but have
stumbled across a problem.  It seems as though when I call
"Print[list[i]]" in a Do[] loop (where i is the iterative variable) it
returns the following: {0.,.2,.4,.6,.8,1.}[i] i.e. it hasn't referenced
the one element I require for computation in the rest of the code.

I try to evaluate a function f[x] at x=list[i], which returns:
Cosh[{0.,.2,.4,.6,.8,1.}[i.]]+....bla bla bla so it seems that it
interprets i as a decimal and NOT an integer, is this the cause of the
problem or is there something else I am doing wrong?

Thanks
Paul
