Hope this isn't another dumb question but ....

I have a business rule object that has a rule which simply compares the sum of several fields in the view with a total that the user entered in the form (the tot is saved in a property on the form).

I tried something like:

if v_invoice.ext + v_invoice.tax + v_invoice.extras <> thisform.nTotal

which blew up because there is no form in the business rule class! So I'm using _screen.activeform.nTotal instead. Is this the best way to reference the property?

Thanks
