[AccessD] mailmerge Format Yes\No

Hello Group,


i use mailmerge for creating word-documents from access.
This is done by using code.

The following line is a peace of this code:
item("Drawing").value = Nz(Me![txtDrawing])

in word i use the following code with properties
{DOCPROPERTY "Drawing" \*MERGEFORMAT}

txtDrawing is a checkbox. In the word-document i get as result: -1 or 0

i would like Yes \ No or in Dutch Ja \ Nee

i tried things like:
item("Drawing").value = Format(Nz(Me![txtDrawing]), "Ja \ Nee")

or

{DOCPROPERTY "Drawing" \@"Ja \ Nee" \*MERGEFORMAT}

with no result.

How can i get the good format?

TIA
