Calculation help !

[elfin2771]

Can someone help me with this one?

I need a calculation that will cancel ont an entry whene a yes/no is entered.

e.g. When the premium is paid "yes" is entered. We would like the premium amount to be cleared and the total to change. (I've got the total field working)

Premium I.P Tr T.P.D Super Total

Nett Prem. $5000. $990 $1180. $7170

Paid

Premium I.P Tr T.P.D Super Total

Nett Prem. $5000. $990 $5990

Paid Yes
