Hi,

Is there any way to create custom task component that should be displayed in related object  in salesforce.

How to write validation for when lead status is working then mobile or email is mandatory?

I wrote this validation like this:
--------------------
AND((ISPICKVAL(Status ,"Working"))
OR(
ISBLANK(Email),ISBLANK( MobilePhone )
)
)
---------
But nor working , it is asking for both
