Are you sure that the entry you have selected in Maximizer has a last name?
Or is it a company entry and you are trying to add contact merge fields? (first name, last name, salutation e.t.c.)
What version of Maximizer are you using? in version 7 and 7.5 you can very quickly identify if this is a company, individual or contact.
A quick test reveals that picking 'last name' when you have a company selected in Maximizer reveals nothing, but selecting an individual or contact in the address book list (important this one, selecting a contact in the contact window will just say 'the action cannot be performed when the current window is active' when you click the Merge Field option in Word)
These are all flaws with the Maximizer Word integration as it uses DDE (Dynamic Data Exchange OR Direct Data Entry) links, which means you have to have the client entry selected at all times during your work in Word, especially if you want to print e.t.c. as 'DDE' is a live link
You may have selected 'Fred A' and created a letter in Word, done all your work, and then went to print, but you had also changed to a different contact in Maximizer because someone phoned up and you wanted to view them in your database.
What would happen now is when you click print in Word it would come out of the printer with the name of the person that phoned up not 'Fred A'
However, can i tempt you to try a different Maximizer Word intgrator called 'MaxDoc'?
It doesn't use 'DDE' intead it uses 'OLE' (Object Linking and Embedding) this is its selling point from a technical perspective amougst other superior features included in it when compared to other Maximizer Word integrations as with the OLE implementation you select a contact, if you have a template already created and stored in MaxDoc's Network Shared Templates folder then you pick it and merge to it automatically giving you a complete letter with contact details and no worry of having to change to a different contact in Maximizer as it isn't effected by this.
Finally, you can also merge one template to as many clients as you want (10s 100s 1000s?), all at once and automatically without having to click 'Next Entry''Print'Next Entry''Print'e.t.c! like you have to with the current Maximizer Word link BUT with only with one click of a button just like the functionality of the Maximizer Editor but with the power of Word!
many people what to mail merge with graphics on the letter header and signature graphics, with MaxDoc and Word you can do this, the Maximizer Editor won't except graphics.
Anyway enough of me, try this link CABC Add-Ons
and click 'CABC Max Document Management'
