conditional statements

I have some code that I would like to run if the following conditions are met:
if (HighValue!=LowValue or HighValue!=-MAX_VAL or HighValue!=0){run code}

I was assuing this means if any of these are true the code will not run, but the loop runs even when a condition is met (ie HighValue==-MAX_VAL which means the code shouldnt run.
The statement I used is the following:
if (HighValue!=LowValue || HighValue!=-MAX_VAL || HighValue!=0)

Maybe I am confused or have been looking at it too long, but I'm stuck and figured a fresh pair of eyes could find the problem.

It looks like you want to use && (AND) rather than || (OR).

Even though your formula is mathematically correct, it won't work due to the way the PocketC (and other C's) work.
What happens is, that the program starts evaluating from either right or left, and as soon as 1 of the OR-statements evalute to true, the task is being run.
The problem is that in order to run at the right time, all the evaluations would have to turn out true, and that can't happen as your sentence is contructed.
