Reset input fields during reload

[#1]

Is there someway to reset input fields during reload without macro? Can I put this in the script somehow?

[prieper]

SET YourField = NULL();

In the beginning of my script I now have for example

inputfield MyField;

LOAD
MyField
FROM SomeTable;

And in my table I have the expression

inputsum(MyField)

Do you mean that if I put

SET MyField = NULL();

in the script the changes I make in the inputfields get changed back to what was loaded in the script?
