Breath Weapon Macro for 3.5

I know i posted a question a few months ago about a macro i was working on for a breath weapon but i need to expand it and made my macro bar more condensed.  I plan to have 3 metabreath feats that change the number of turns the cool down for the next breath weapon.  I have a rough idea of how to start it but not to go about writing it. I know I will need to use the same code as the ones used in full attacks but i am unsure of how to do that.  &{template:default} {{name=breath attack}} {{attack=[[ [[ floor(@{level}/3)+1]]d8 ]]}} {{Cool down= [[1d4]]rounds}} {{Saving Throw= [[10+floor(@{level}/2)+@{con-mod}]]Reflex for half }}  this is what i use currently for my breath weapon. I don't really want to have different macro buttons for each metabreath combo because that would result in 6 different macro buttons for the same basic attack. 

What are the three feats and what are their effects on the cd?

shape breath increases the CD +1 maximize breath increases CD +3 quicken breath increases CD +4 special note maximize and quicken can not be used at the same time 

{{Cool down= [[1d4 + ?{Shaped?|No, 0|Yes, 1} + ?{Other?|No, 0|Maximized, 3|Quickened, 4} ]]rounds}}

Thank you. I am still learning everything you can do with the Macros. 

So, the ?{} is a query. It asks you for an input. ?{number?} would simply ask you to type a number. ?{Number?|0} would ask for a number, but autofill the box with 0. ?{Number?|0|1} will instead create a drop down with the options of 0 or 1, with each | adding another option.  See  her e for more info

ok that makes sense. Thanks again.
