Um -- I must be missing something here, because those two statements have exactly the same effect on $Count, incrementing it by one (and you said the first statement fixed your problem, so logically the second one must too). In fact, because you've used a post-increment, the statement $Count1 = $Count++; ends up with $Count == $Count1+1, and $Count1 being the original value of $Count!! This whole scenario smacks to me of a classic "off-by-one" error -- either $Count actually *needs* to be one greater than the value you first thought of, or some other value you are comparing it to should be one smaller than it actually is.
