Anthony,
Look up Prime and PrimePi in Help.
For a sum using only primes <= 100....
Sum[f[Prime[i]], {i, 1, PrimePi[100]}]
f[2] + f[3] + f[5] + f[7] + f[11] + f[13] + f[17] + f[19] + f[23] + f[29] +
f[31] + f[37] + f[41] + f[43] + f[47] + f[53] + f[59] + f[61] + f[67] +
f[71] + f[73] + f[79] + f[83] + f[89] + f[97]

Can you tell me if, when calculating a summation of f(i) where i goes from
imin to imax, Mathematica can be forced to only use prime values for i?
Thank you for your time
