Help with script

[mmgiath]

Here is my problem:

I have two numeric fields A and B.

Also I have a Total numeric field that calculates

NumericFieldA.rawValue - NumericFieldB.rawValue;

On a click event for a button I have the script:

Remove.execEvent("click");

WITH THIS BUTTON(Named: Remove Data Button) I REMOVE DATA FROM FIELD A TO B.

For a hidden Button(Remove) on click event:

NumericFieldB.rawValue=NumericFieldA.rawValue;

NumericFieldA.rawValue=null;

my problem it is when I remove the data from FieldA still in the Total field there is a value!

How I can remove this value at the same time when I clck on the Remove Data Button?

Just I want to be BLANK.

Thank you for your help!
