How to validate input value in oracle fusion hcm?

Bishoy Talaat

I have a requirement to validate the user's input on weight field on goal screen before submitting.

I created sandbox and I am trying to add EL Expression to validate the input.

validation is : Input value to be multiple of 5

and show error message if the input is not multiple of 5.

the expression i use is :

 #{bindings.Weighting.inputValue mod 5 != 0 ? 'x': 'Y'} but i doesn't work fine.

Thanks in advance.
