Looking for Answers about AVERY Manage Your Large-Scale Mailing with Ease?

Word 2003 offered a means to add a destination barcode to my envelopes. I am now using word 2010, is it possible to add the same barcode to my mailing labels.

I have downloaded Avery DesignPro, whic give me access to my Access files for barcoding, but it will not recognize my column names. As an example I have a column named "Last Name", which throws an error every time I try to import a column which states "The column "Last Name contains an invalid column, and so on where there is a space in between the first and last part of the column name. I would change the name, but that would throw all of the programs that use this database out of sync. I would imagine that more and more access databases are desihning with this structure. I guess there is no simple means of accomplishing my task.
Also, It would probably be beneficial with Avery DesignPro to include a template with a regular address label as you do with the regular label program.
Thanks in Advance!
