Fields on a form merging to Word

[harrisw]

Trying to merge a field on a form to a word document using
.ActiveDocument.Bookmarks("fieldname").Select
.Selection.Text = (CStr(Forms![frmMain]![subfrmMainCompetitor].Form![fieldname]))

The field in question is a combo box and all that is being merged to the word doc is the bound column number and not the field contents.

Any ideas?
