Its Been a while but Im back (Pathfinder Macro help)

So um I'm a bit confused as to how I would exactly do the Macro for this For every 2 caster levels beyond 3rd the caster possesses, the rune deals an additional 1d4+1 points of fire damage (2d4+2 at caster level 5th, 3d4+3 at 7th, and so on) to a maximum of 5d4+5 points of fire damage at caster level 11th. I so far have this Damage: [[ floor( {@{spellclass-0-level-total}*.5,5}kl1 ) ]]d4+[[ floor( {@{spellclass-0-level-total}*.5,5}kl1 ) ]] Thanks ahead of time for all the help :D

[[ [[{1, [[ {5,[[  floor(( (@{ LEVEL_ATTRIBUTE })-1)/2)   ]]}kl1 ]]}kh1 ]]d4 + [[{1, [[ {5,[[  floor(( (@{ LEVEL_ATTRIBUTE })-1)/2)   ]]}kl1 ]]}kh1 ]] ]]

Maybe try this..?? Should provide the correct outcome... [[ [[ {5, floor((@{spellclass-0-level-total}-1)/2)}kl1 ]]d4 +( {5, floor((@{spellclass-0-level-total}-1)/2)}kl1) ]]

yours shows up better..... :)

Thanks guys :D

So both of your ideas work out. I was wondering if this would work out just as well though or if either of you notice anything that would break something? [[ floor( {[[@{spellclass-0-level-total}-3 ]]*.5,4}kl1 ) +1 ]]d4+[[ floor( {[[@{spellclass-0-level-total}-3 ]]*.5,4}kl1 ) +1 ]] Since the spell in question Fiery Runes "Explodes" on a melee attack after being attached to a weapon so I would be rolling the damage at a later date
