Automatic Update for a Fetched Item

1

Hi,

I have a field “Price” in a customized Form that fetch the price of an item from the Standard Rate, and it is working fine with the new entries.

But when the standard rate changes, the field “Price” doesn’t update automatically.

So, how can I let it be updated automatically.

Thanks
