Indian comma in excel in positive numbers as well as in negative

[shrinivas]

For lakhs & ten lakhs the below formula works fine.
[>=10000000]##\,##\,##\,##0;[>=100000]##\,##\,##0;##,##0

In case the same I need in negative figures like (1,00,000). I do not get
it. Can someone explain me. Can I know the formula.

never thought about this but try adding

and([<-100000],[>-1000000])


(you add the #####,## stuff)
