"Member not found" when trying to transfer Scout from a Pack

I’m trying to initiate a transfer of member ID 136276590 using the “transfer in” tool. However, when I type in their member ID, First and Last Name, and Date of Birth, I get the error, “Member Not Found” with the second line, “We were not able to retrieve information from the memberId”.

Do you have any thoughts on what could be going wrong? The Scout does have two last names, but I’ve tried every combination I can think of on where to put each name, omitting one of them, etc.

last name is C### (space) L#### - that being said - not sure if the system can handle a double last name
Perhaps the Pack can do it from my.scouting.org for you
