Hi, experts

Please, help me if you can.
Every time I change cell value on other worksheet than the one where
selfwritten function is called and if this cell rules any argument
calculation I'm getting 0.0 or #value. Once I put cursor into my function
calling cell and push enter it recalculates. What should I do to force it
recalculate automaticly?
I searched for my problem here and found that I should add Application.
Volatile.
It helped but only partly. Before I had to manualy recalculate (put curcor
and push enter) every cells callin my function. Now I need to do it only in
one cell and other on the same sheet recalculate.
Is it possible to recalculate my function when any cell in entire workbook
has been changed?
