Is it a calculating cell (light blue or conditionally formatted, if you click on them they have some sort of formula in the cell)? Is it a validity cell (light gray, when you click on it you get a drop down box)?
The metagame calculator uses User Defined Functions now so that I can take into account a large amount of variables using code instead of using excel. This is my first time using them so I have no idea how it reacts when placed on other peoples computers.
I can update everything in the spreadsheet for heartgold and soul silver in about 5-10 minutes assuming that the movesets are posted on smogon and the learnsets are posted somewhere.
