Listnu m Office 2002 vs Office 2003

[Gert Raes]

I don't know if this is a numbering issue or a mailmerge issue, but here it
goes:

A customer has created a mailmerge document with a listnum field in a IF
Then Else-statement, which looks like this :
{IF {Mergefield M_1} = "" "" "{Listnum OverzichtStandaard \l 3} {Mergfield
M_2}"}
{IF {Mergefield M_3} = "" "" "{Listnum OverzichtStandaard \l 3} {Mergfield
M_4}"}

When he merges the document in Office 2002 SP3, he gets this result :
1. (content of Mergefield M_2)
1. (content of Mergefield M_4)

When I merge it in Office 2003 SP1, I get :
1. (content of Mergefield M_2)
2. (content of Mergefield M_4)

Is this a known issue or is it a setting in Office ?

TIA,

Gert
