I still don't know what your doing there but here is my way of returning
random number within my own limits.

first theres this function called rand();

int number;
number =3D rand() % 100;

^^^^^^^^^^^^^^^^^^^^^^<<-- this producues a number from 0 to 99

now pretend you wanted a number from 25 to 35.  First you subtract the
high number from the low number 35 - 25 =3D 10... so =


number =3D rand() % 10;

that produces a number from 0 to 9, but we want 25 to 35... so what you
do is add 25.  25 + random number from 0 to 9.  WAIT! that only goes
does 25 to 34... so.. just add 1 !!! :)  so the whole thing put together
is

int number;

number =3D (rand() % (highNUM-lowNUM)) + lowNUM + 1;

got it... i hope that helps with the random number question you have...
or either that I have no idea what Im talking about and have totally a
whole bunch of mistakes about random number and I am about to get flamed
about my stupidity :)

later
