Thanks...

If [as I am assuming] your intention is to calculate the sum of the High plus the Low and divide the result of that by 2 then the equation high()+low()/2 is written incorrectly.
As is the value returned by the equation is that of the High plus the result of the Low divided by 2 (divisions and multiplications are performed before additions and subtractions) so you need to enclose high()+low() in parenthesis to perform the calculations in the desired order (anything in parenthesis is done before divisions and multiplications)
