That part of DTTC was introduced in excel 2002, he can use a macro like
Sub Conv_Trail_Minus()
Dim cell As Range
For Each cell In Selection.Cells.SpecialCells( _
xlCellTypeConstants, xlTextValues)
cell.Value = CDbl(cell.Value)
Next cell
End Sub
press alt + F11, insert>module and paste the above,press alt + Q to close
VBE,
select the numbers and press alt + F8 and run the macro
or a help column and a formula
=IF(ISNUMBER(FIND("-",A1)),---SUBSTITUTE(A1,"-",""),A1)
However I really don't understand the OP when he says don't show up, are
they not there?
If that's the case I haven't got a clue

For everyone's benefit keep the discussion in the newsgroup.
