I have 2 currency fields in screen. Initial cost and Total cost.
total cost is a display field. and its value is
total cost = initial cost * time taken.
My problem when i put the initial cost as zero and total cost is coming up zero. and when i go to next screen and come back to the same screen the inital cost is becoming blank. but if i give initial cost as 20 and final cost is caluculate and coming up and when i go to the next screen its not geeting erased. The inital cost should take the value 0 it should not get erased.
