Hi,

you must set the seed-value for the random number generator
before you start the generator. In Mathematica this is done with

SeedRandom[n] resets the pseudorandom number generator, \
using the integer n as a seed. SeedRandom[ ] resets the \
generator, using as a seed the time of day."

Regards
