Ability Effect Questions for 3.5/Pathfinder

[Farnaby]

I have a Paladin with a Smite Evil effect.
This adds the charisma modifier to the attack and level to damage also it reduces the AC of the opponent by the charisma modifier.

So I created 2 effects, 1 to the character and 1 to the opponent.

One is: Smite Evil; ATK: [CHA]; DMG: 1
The other is: Smite Evil; AC: [CHA] deflection

My first question is how can I get the damage to reflect level instead of manually inputting it?
Secondly, how do I get a negative ability? -[CHA] and [-CHA] both don't work.
The first gives me AC: - and the second just AC:

The other one is the burning hands spell which looks like this: d4 x CL
Now I have a feat that lets me add 2 CLs to the equation, in other words d4 x (CL+2)
Any idea how to do this in the SPELL/ABILITY DAMAGE window?

Any help would be appreciated.

[-CHA] should work, but only if the effect is edited in the character sheet and then added to the combat tracker as the code that adds the effect to the combat tracker replaces the CHA with the numerical value. Adding [-CHA] to an effect already in the combat tracker doesn't do anything.

Also, this functionality only worked from FG 3.0.11 onwards, and if you're using an extension for prior to that you might not have he most up to date code. Update any extensions related to effects to ones compatible with 3.0.11+
