mail merge excludes my headers and critical data in Word merge
 

I am attempting to do a routine mail merge (I do these weekly with no
problems until now) using an excel datasheet as my datasource in a word
document. I restored the program to make sure it had nothing to do with an
internal error. I also checked the data for errors, which it indicated none.
Is there some small thing I am missing here that would take care of this
problem I have not encountered before?
