Nadya,

Thanks, you gave me one solution that when the old value for ie. 2000 and I want to replace it with 1000, the changes will not gonna be 1000000 (the digit 2 is replace by 0 (the last zero from 1000)) but the old value 2000 stil there.
Can you give me any idea how to clear it as we want to make changes ?

TIA

Budianto
