A filter expression gets evaluated not at time when you issue SET FILTER but when attempt is made to move record pointer in a table. At this time THIS.Value cannot be resolved anymore.
The code below should fix the problem:

lcLikeExpr = ["*] + ALLTRIM(THIS.VALUE) + [*"]
SET FILTER TO LIKE(&lcLikeExpr, MyMember.E_Name)
