Spells Per Day Macro?

I am not using a spellcaster per se, but I was curious about how to calculate the Spells Per Day on the Roll20 System for D&D 3.5. I am thinking of using the Spells Per Day Option as The Ki Pool of my Ninja Character, but found no way of doing so.

since 3.5 / PF spells per day is dependent not only on your level, but also your class and attributes(for bonus spells) I don't think you're going to get that through a macro calculation. Sometimes macro automation just isn't the way to go. That being said, I've seen folks come up with ridiculously complex mathematics to get the job done. (*cough* Gauss *cough*) so don't lose all hope yet :) If you want a macro that displays your spells/day I would then recommend you store that values as Attribute values and have the macro reference it. What I do, myself, is just type it out on my character sheet's Bio tab and adjust it as I go.

What i stole from another GM (saevar) was to make a couple decks of cards, for example make a deck called level one spells, select a picture to represent level one spell slots, and then handout X number of cards to that player. Whenever he/she casts a spell that player just drops one of their cards from their deck onto the table top. While this won't auto calculate anything it will def help keep track of spells used between sessions.

kewl Idea with the card thing. However Since I can't create a macro on the site for the spells per day I thought I could simply use the Blue circle on the Token to reference my Ki Power, and alter that as I go.
