Power attack macro Pathfinder sheet

So... Im trying to figure out a few macro that will do power attack One for the negative attack penalty that grows +1 for bab 4 and then every 4 afterwards one for the Positive damage that starts at 2 and grows to +2 at bab 4 and +2 every 4 bab after and one for the Positive two handed damage that Starts at 3 and grows for +3 at bab 4 and every 4 after Thank you ahead of time for the assistance

attack(negative energy) -[[ (floor(@{selected|bab}/4) + 1)*?{negative energy?|yes, 1|no, 0} ]] damage(positive damage) : +[[ ((floor(@{selected|bab}/4)*2)+2)*?{positive damage?|yes, 1|no, 0} ]] damage(2-handed positive damage) : +[[ ((floor(@{selected|bab}/4)*3)+3)*?{2-handed positive damage?|yes, 1|no, 0} ]]

Thanks Vince :D
