Thanks ,Julie. First this question is not related to first one.second part
you are right,whenever I click cell A1 I can type a new value that will add
previous value in that cell.Third part ,why I need user form /table when I
click that cell,let me explain my task.
col A-------col B-------------col C------------Col D
item -------Qty.Ordered----Qty.supplied----Balance to supply
Milk---------15000 litrs------200 litrs-------14800
whenever I click C2,a form wiil populate where in I will enter today's date
and qty supplied, current supplied qty will be added to Col c2 qty.col B qty
is fixed for one year.Col D is calculation.Col c qty details will populate
whenever I click that cell so that I can view last quantities also.
This is my task
