How make a Supernatural ability's Base Charges = class level?

[draco963]

Hello,

I'm making some supernatural abilities that are going to require me to have the base number of charges that the player gets for the abilities to equal 1 rnd/day per class level.

So, the Base Charges field in the [B]SPECIAL/B] tab allows for a number, and then Usage period has rounds/day as an option. All good so far as it goes. But what I need next is for the number in Base Charges to equal a certain class's level on the character.

I presume I'll have to do this with an eval script, by fetching the characters number of class levels, and then making the Base Charges count equal the number. But I'm clueless as to how to achieve that...

Thanks in advance!
