Hi , I am trying to use lookup function in form O365 with classic designer.Here I am providing relative URL as first parameter in lookup function eg-

lookup("/sites/Alpha-Gamma|Employee", "ID", EmpId, "EmpName")

But it is not performing the lookup.If list is at same level , then only I am able to see the looked up value ?

Pls suggest what am I missing and what I have to do to successfuly pass relative path in the lookup function ?
