I have no idea what I'm doing or how to fix it.  Someone made some forms
years ago. Now something is wrong with them and I've been asked to fix it.  
The person that made the form is not here. I'm getting error reports and when
I tell it to debug this pops up. and the polnum = .DataFields("... is yellow
with a small yellow arrow.

What do I do about it?

With ActiveDocument.MailMerge.DataSource
   .ActiveRecord = wdFirstRecord
   Agenttest = .DataFields("Agent").Value
   polnum = .DataFields("PolNum").Value
   sdate = .DataFields("startDate").Value
   edate = .DataFields("endDate").Value
   'checkadd1 = .DataFields("Address1").Value
   'checkadd2 = .DataFields("Address2").Value
 End With
