AddCommas() is what inserts the locale-dependent separator as stored in LARGE_NUMBER_SEPERATOR. This global is what's used in the Default UI code for BreakUpLargeNumbers(). local ReformatNumberString; do     local AddCommas(pre,post) return pre..post:reverse():gsub("(%d%d%d)","%1"..LARGE_NUMBER_SEPERATOR):reverse(); end     local SplitDecimal(str) return str:gsub("^(%d)(%d+)",AddCommas); end     function ReformatNumberString(str) return str:gsub("[%d%.]+",SplitDecimal); end end

Thanks very much everyone for going out of your way to help.

Special thanks to Phantom... i'll give that code a wee try today
