I had a problem with the sharepoint form, I want to get the username by userProfileLookup and I used this function
I actually tried everything, all functions like "DisplayName", "First Name", "LastName" and "UserName"...etc. But all of them didn't made any difference, still they return #Value
try using single quotes userProfileLookup(Current User,'PreferredName') also try publishing it and checking the actual form but not in preview mode. Shouldn't be a reason why it's not working. You can also try instead of Current User variable, use and actual domain/user to see if it has something to do with that.
I tried it too now and still no use ):
someone told me the problem may be from the directory
because everyone have the same problem in my team
I think this is the only solution remain
In order for it to work you have to select the "CurrentUser" variable from the right. You can't just type it in. If you've don it correctly it will show in red. You tried it that way, right?
