Look up multiple values from one cell

Hi , Charlie1234 

According to your description, you want to lookup value from one table by ids , and in a row , you have multiple ids.

For your need , here are the steps you can refer to :
(1)This is my test data:

(2)We can click "New Column" and enter this:

Column = VAR Items1 = SUBSTITUTE ( [IDs], ",", "|" )
VAR T1 = GENERATESERIES ( 1, COALESCE ( PATHLENGTH ( Items1 ), 1 ), 1 )
VAR T2 = SELECTCOLUMNS ( T1, "@Item", PATHITEM ( Items1, [Value] ) )
var T3 = ADDCOLUMNS(T2, "name" , LOOKUPVALUE('Name'[FirstName],'Name'[ID],VALUE([@Item])) & LOOKUPVALUE('Name'[LastName],'Name'[ID],VALUE([@Item])))
return
CONCATENATEX(T3, [name] , ",")

Then wen can get this:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
