Hi Tim,

Basically we need a data validation engine for document submission in our web app. Kindly refer to the following exmaples.

(i) If Control A.value > 10, then Control B must be filled up.
(ii) If Control A.selected value = X, then Control B can't enter certain values.
(iiI) If Control A.value is empty, then Control B can't be selected.

We would like to design the validation engine to be data driven as the rules of the validation may differ for each client. At the moment, we plan to write a generic function which will be executed before the MM.Save() method and pass the BO to our VFP COM for validation.

Appreciate if you could provide any valuable advise, thanks.
