So I have one list name Electronic Filing Credentials for ECF, my formula is added to a calculated field I have a people picker column call HHR Name and a date column called "Date PAA Added and nested within the lookup is a userprofile lookup. So essentially in my Nintex form you put a person's name in People picker that date shows up. The formula looks like this and it works fine.

lookup("Electronic Filing Credentials for ECF", "HHR Name" , (userProfileLookup(HHRName, "PreferredName")) , "Date PAA Added")

Now the problem is that Date PAA Added field isn't always filled out.  A user can have multiple entries in the list and depending on another column called "Credentials Type" (a choice field with three choices, PACER, State, and Federal) depends on if that date field is populated. And if any of the fields are blank then the formula does not work and that calculated field is blank.

So basically the ask is can I also filter within that formula based on that Credentials Type column if it contains Pacer that it will show up in the calculated field. Hope this makes sense. Thank you in advance.
