Excel 2003 :: Take Specific Text From Cell And Copy It In New One (Text And / Or Words Position Varies)

I'm having a 6000+ records, (contacts DB) exported in Excel 2003 format from MS Outlook.

Except the "First" and "LastName", all other contact elements are in the field "Notes" (which is the BZ column according to the exported outlook layout) multiplied by 6469 (records in total)

Useful information are included !!!

I'll give an example of a record...

Column: BZ, Row: 543 says --> "2110000000-6989000000, 1TOK_TER:17-11-010(25 DAYS LESS),
KATERINA 25 (MANTAS KALNNNNN_HYPERTENSION)1000-150, W:95_105, , HR THE 16wks_US NEFRON OK,
NT OK_B EPIP OK(GOLF BALL)_KAMPILI ORIAKI(DIAITA)_DOPPLER OK, O+,TEST OK(TOX_), , , , , , "

Now, I want every time to take the part of the text says "TER:something..." (part of which is date, but not every time with the known format dd-mm-yyyy, as you see here is yyy, followed by something else, with parenthesis here and maybe more data) and copy it in a new cell..., e.g:CO Column, same Row...

Above and every field which by the way is formatted as General (and it is text mainly) are made by merging older excel fields where data laid here and there, that's why you see the commas...with the method of a module with the following code:

Function MyMerge(Rng As Range)
For Each Cell In Rng
Temp = Temp & Cell.Value & ", "
Next Cell
Temp = Mid(Temp, 1, Len(Temp) - 2)
MyMerge = Temp
End Function

Note1:Records with the above string (TER:dd-mm-yyy) are 771 from 6469.
Note2: As an alternative solution I can see an extraction of the TER:dd-mm-yyy string and the copy in a new place, like the:CO Column, same Row...
