Suppose I have the follow table and field structure:
Field C is a calculate field where A are multiplied by B.
What I need is to change the value of field C by hand if I don't like the result of the calculation.
Since field C can't be modified because is a calculation filed.
I tried to setup a new field D where D is a number field and setup the auto enter a calculation where the field D is equal to field C. and check the don't overrigth if there is a value. So I can change the value if I want and clear the field to show the calculated value, but....
But the field keep always empty.
PS. Sorry for my English.....
