Error in ConcatRelated - string-concatenation

Question

Here is my table structure:
ID1 - autonumber
TDate - Date/Time
TTime - Date/Time
TID - Text
TMessage - Text
Tcode - text
TMessage value can be 100+ characters. There can be more than 1 TMessage for each TID
Sample input:
TDate TID TTime TMessage
1/9/2014 93378 12:28:28 PM aaaaaaaaaaaa
7/24/2014 02645 12:56:22 PM bbbbbbbbbbbb
7/24/2014 02645 12:56:30 PM cccccccccccc
Output should be:
TDate, TID, TMessage
1/9/2014 93378 aaaaaaaaaa
7/24/2014 02645 bbbbbbbbbb,cccccccccccc (the output can be more than 255 chars.)
This is my query/module (got from Stackoverflow and Allen Brown)
Query (SQL View)
SELECT sub.TDate, sub.TID, ConcatRelated("[TMessage]","RawData2","[TDate] = '" & sub.TDate & "' AND [TID] = '" & sub.TID & "'","[TDate], [TID]") AS concat_Message
FROM (SELECT q.TDate, q.TID FROM RawData2 AS q GROUP BY q.TDate, q.TID) AS sub
ORDER BY sub.TDate, sub.TID;
Function :

'Purpose: Generate a concatenated string of related records.
'Return: String variant, or Null if no matches.
'Arguments: strField = name of field to get results from and concatenate.
' strTable = name of a table or query.
' strWhere = WHERE clause to choose the right values.
' strOrderBy = ORDER BY clause, for sorting the values.
' strSeparator = characters to use between the concatenated values.
'Notes: 1. Use square brackets around field/table names with spaces or odd characters.
' 2. strField can be a Multi-valued field (A2007 and later), but strOrderBy cannot.
' 3. Nulls are omitted, zero-length strings (ZLSs) are returned as ZLSs.
' 4. Returning more than 255 characters to a recordset triggers this Access bug:

Currently, this is the output:
TDate TID Concat_Message
1/9/2014 93378 #Error
7/24/2014 02645 #Error
7/24/2014 04533 #Error
Question 1 - What could be the reason for the Error? How to solve it?
Question 2 - Can I just create a table manually with Memo field so I can store the result of the Query to this table?
