partail confirmation: part 2

hi all

when i am partially confirming an activity say 50%, and insering the actual start and finish dates...with forcast duration ............and saving the activity, these are getting projected on to my project planning board.

till now its ok,

now when i am going for confirmation for the same activity, its showing 100% by default.............its not showing the % which i have confirmed earlier ..................now i dont know, how much i have confirmed earlier ...............................any solution for this

where am i going wrong?

Regards
