I have a problem with ms excel 2007. actually i have more than 10,000
records.

data entry function formula results
a1= 5, b1=1; -- c1==a1*b1 = c1= 5
a2=10,b2=4; -- c2==a2*b2 = c2=40
a3=8, b3=8; -- c3==a3*b3 = c3=64

but my output comes out differently.

the function formulas are the same but the results are differently.
they came out as the previous result. but when i double click it to
see the formula and enter back again, it auto refresh the data for me.
why it happens like that? i want to copy from the previous functions
and paste into new one and just changing the cell reference not the
answers from the previous cell. i have more than 10,000 cells with
records. is it i have to do one by one? please help me. it's really
urgent. thanks
