How to apply validation

Hi,

I have created one form with the chronoform component and its working fine but i want to apply one validation check to two
fields..
The form contains one dropdown menu that contains two values A and B ,and next to that one email texbox field also there.
What i want is when the user select A from the dropmenu then the user must enter the email field otherwise don't save the data.

Please help me how to apply the code ...

Thanks
N

Hi Naufal,

you need a custom validation rule written based on your fields names, please search the forums here, some posts have rules written, the rule will have some text like "LiveValidation"

let me know!

Cheers,
