Can someone tell me why my fields aren't being populated other than my subject field? I am trying to clone a task. I created a URL button on Task object. Here is my code:
/lightning/o/Task/new?&defaultFieldValues={!IF(NOT(ISBLANK(Task.What)),'&WhatId=' + Task.What,'')},
{!IF(NOT(ISBLANK(Task.Who)),'&WhoId=' + Task.Who,'')},Subject={!Task.Subject},
Priority={!Task.Priority}, Description={!Task.Description}, Status={!Task.Status}
