Spent a long time searching hoping to find this, but everything I see is trying to fetch other data with VLOOKUP. Since I just need a count of matches, I just need it to return True or False.
Two Sheets named 'X' and 'Y'. Trying to match Column A "FirstName" and Column B "Last Name"
For example, if someone on Sheet B is name John Smith, I need to see if someone on Sheet A is also named John Smith (with both names being on the same row). If so, return true.
