MODULUS is "remainder" math. for example, x= 25 if x mod 5 then '.... end if 25 goes into 5 5 times (exactly) with 0 remainder. add one, 26 goes into 5 5 times, with 1 remainder. so when you do your test for x mod whatever, it needs to = 0 to be true (or, whatever you decide to set it equal to). if your "step" between (ie, 4 to 9, 9 to 14) is not a constant, (in this example, 5) modulus won't work. even your subject line suggest's this :) every nth is a constant N.
