3.5 character sheets - how to change what ability modifier is used for a save/skills

both me and another player in our new 3.5 game are having an issue in that our classes have features that mess with what ability modifiers effect our saves (me) and skills (them). i have figured out how to mess with the roll scripting so it at least puts in the correct numbers (added a function to subtract wisdom mod and then add back in cha) but that doesnt effect the number statically displayed and i have sited it wrong to DM a couple times so just want to fix it

Hi Micheal A.,  Which character sheet are you using?  If you don't know the name of the 3.5 sheet please supply a screenshot so I can identify it.

he says he just selected the first on the list but that there are 2 others , adventure pack and black company. 

Sorry for the delay in response. Life :) That character sheet is named the "D&D 3.5e" sheet, it is by Diana P.  Could you show me screenshots of the stats you are using, and the result in the chat tab? Basically, I need to know which ability name, that modifiers involved, etc.
