In Microsoft Word 2002, when you try to return a merge field by using the MappedDataField name, and your data source is an Outlook contacts folder, you receive the following error message:
Run-time error '5941': The requested member of the collection does not exist.
NOTE: To view or modify mapped data fields in a mail merge document, click the Match Fields button in the Insert Merge Field dialog box.
This problem occurs if the MappedDataField name you are returning contains more than one word, such as the Business Fax, Zip/Postal Code, Home Fax, Email Address and Web Page fields in Outlook.
Microsoft Word replaces any spaces in a mail merge field with an underscore characters (_). However, when using Outlook contacts as the data source, the returned names from the MappedDataFields do not contain these underscores.

When you want to return the merge field for a MappedDataField object, use the DataFieldIndex property instead of the DataFieldName property.
NOTE: The following sample macro uses the DataFieldIndex of a MappedDataField constant (wdBusinessFax) to determine the fax number for the first record in the data source.
Sub mappeDField()Dim objDsource As MailMergeDataSourceDim BFAXindex As IntegerDim objBFX As MailMergeDataField 'Return the mail merge data source. Set objDsource = ActiveDocument.MailMerge.DataSource With objDsource 'Set the first record as the active record. .ActiveRecord = wdFirstDataSourceRecord 'Return the index for the wdBusinessFax MappedDataField. BFAXindex = .MappedDataFields(wdBusinessFax).DataFieldIndex 'Return the corresponding mail merge field. Set objBFX = .DataFields(BFAXindex) 'Return the business fax number. MsgBox objBFX.Value End WithEnd Sub
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
In Word, a mapped data field represents a commonly used name or address information, such as "First Name". If a data source contains a "First Name" field or a variation (such as "First_Name," "FirstName," "First," or "FName"), the field in the data source will automatically map to the corresponding mapped data field in Word.
