How to remove an initial value (0) from a "Numeric Entry" field

hi! friends

it very simple to remove default value  "0"  in numerical entry.

1. take a numerical entry.
2. make text variable type as" my".
3. double click on that numerical entry's trigger.
4. assigned the text variable. simple.

Good think is this---:    after assigning text variable, numerical entry take only numerical entry instead of text..

i think, its helpful for you.
